Best music apps: Last.fm
Last.fm made its name through its desktop service that "scrobbles" or records a user's listening history and provides statistics and music recommendations based on the data it collects. It also provides a personalized radio mode that can be set to play music similar to a given artist, genre or other "tag" as well as a radio of just the user's previously scrobbled tracks.
Last.fm's mobile effort incorporated these features into its apps for Android and iOS-enabled devices for free until February, when it began charging for the content. Users with premium accounts for the desktop version of last.fm can listen to ad-free, customized radio on their mobile devices.
Unlike Pandora, users do not have song limits or skip limits when listening to radio mode.
However: The premium service does not come with as many features as many of the other music apps on the market. Further, the scrobbling function is not available via last.fm's mobile apps.
