The one or more programs include instructions for detecting a display change associated with media content item represented on a display, transmitting a request (e.g., to a server) for at least a portion of the media content item, receiving the requested portion of the media content item, storing the received portion of the media content item in a local cache, receiving a user input indicative of the selection of the media content item, and presenting the received portion of the media content item in response to receiving the user input indicative of the selection of the media content item.

Abstract: An electronic device with one or more processors, memory and a display receives a first request to display a first video stream that corresponds to a first channel. In response to receiving the first request, the device starts to download the first video stream from a content source for the first video stream. After starting to download the first video stream, the device displays the first video stream and starts to preload one or more video streams including a second video stream that corresponds to a second channel that is adjacent to the first channel. While displaying the first video stream, the device receives a second request to display the second video stream. In response to receiving the second request, the device displays at least a portion of the second video stream using a preloaded portion of the second video stream.

Abstract: An electronic device with one or more processors, memory and a display displays a first video stream on the display. While displaying the first video stream, the electronic device downloads and stores a first portion of a second video stream and receives a request to display the second video stream on the display. In response to receiving the request, the electronic device starts to play the second video stream using the first portion of the second video stream, if the first portion of the second video stream meets recency criteria with respect to a current stream time of the second video stream. But if the first portion of the second video stream does not meet the recency criteria, the electronic device requests a second portion of the second video stream that is outside of the first portion of the second video stream.

Abstract: An electronic device presents a first song that includes a sample of a second song, different from the first song. While presenting the first song, the electronic device displays a preview control on a display. The preview control corresponds to the second song. The electronic device receives selection of the preview control and, in response to receiving the selection of the preview control, plays a preview of the second song.

Abstract: An electronic device with one or more processors, memory and a display displays a first video stream on the display. While displaying the first video stream, the electronic device downloads and stores a first portion of a second video stream and receives a request to display the second video stream on the display. In response to receiving the request, the electronic device starts to play the second video stream using the first portion of the second video stream, if the first portion of the second video stream meets recency criteria with respect to a current stream time of the second video stream. But if the first portion of the second video stream does not meet the recency criteria, the electronic device requests a second portion of the second video stream that is outside of the first portion of the second video stream.

Abstract: An electronic device with one or more processors, memory, and a display displays a first video stream on the display. The electronic device downloads and stores a portion of a second video stream and, once the portion of the second video stream has been downloaded, ceases to download the second video stream. The electronic device receives a request to display the second video stream on the display and, in response, determines whether the stored portion of the second video stream satisfies recency criteria with respect to a current stream time of the second video stream. In accordance with a determination that the stored portion of the second video stream satisfies the recency criteria, the electronic device displays at least a portion of the first video stream on the display concurrently with at least the stored portion of the second video stream.

Abstract: An electronic device displays a first video stream on a display. While displaying the first video stream on the display, the device allocates, in accordance with a historical pattern of video stream switching of a particular user, available bandwidth for receiving data at the device at least between receiving the first video stream and preloading a second, non-displayed video stream. The device receives the first video stream and preloads the second, non-displayed video stream in accordance with the allocated available bandwidth. The device receives a request to display the second video stream on the display. In response to receiving the request to display the second video stream on the display, the device displays the preloaded second video stream on the display.

Abstract: An electronic device with one or more processors, memory and a display receives a first request to display a first video stream and, in response, displays the first video stream. After receiving the first request, the device preloads a second video stream that corresponds to live content, including caching a cached portion of the second video stream. While displaying the first video stream, the device receives a second request to display the second video stream. In response to receiving the second request, the device determines whether the second request meets recency criteria. When the second request meets recency criteria, the device starts to play the second video stream using the cached portion. When the second request does not meet the recency criteria, the device requests, from a content source for the second video stream, data corresponding to a portion of the second video stream other than the cached portion.

Abstract: A client device with one or more processors, memory, and a display displays a first video stream that corresponds to a first channel in a sequence. While displaying the first video stream and before receiving a request to display a second video stream corresponding to a second channel in the sequence, the client device preloads, from a remote content source, video content of one or more intervening channels. In response to receiving the request, the client device transitions from displaying the first video stream to displaying the second video stream: a portion of the first video stream is concurrently displayed with at least a portion of the preloaded video content of one or more intervening channels, and at least a portion of the preloaded video content of one or more intervening channels is displayed concurrently with at least a portion of the second video stream.

Abstract: An electronic device presents a first song that includes a sample of a second song, different from the first song.
