No. 5: Slacker

No mobile roundup would be complete without a great music app, and after much internal debate, we decided Slacker is our favorite. The service offers both curated stations that are organized by theme and genre as well as algorithmically generated playlists based on artists or songs you pick.

As with Slacker Radio on other mobile platforms, the Android app lets you stream music from preprogrammed genres and stations, or create your own stations and mixes using the search feature. You can also view album art and bios, "ban" and "heart" tracks, and skip ahead. The free version of the service has ads and skip limits; you can upgrade to Slacker Radio Plus to eliminate these and add caching capability for offline playback.
