The music sharing Spotify has been overdue to land on the iPad, but now the company has made an app specifically for Apple’s tablet. The app makes it easy to work with the core of Spotify: Users can search for songs, create playlists, share them with their friends and look at their friends’ lists. The app also has a unique iPad feature that makes it easy for users to discover new music. The app features encyclopedia-like entries on bands or individual artists, making it easy to find related artists or link to other projects in which a given musician was a participant. For example, pull up an entry on Bob Dylan and it’s a one-tap road to pull up a separate panel on collaborators like Joan Baez or influences like the Kingston Trio. Users can navigate back to their original search quickly by flipping back through their search chain. This fills a gap left by Spotify’s streaming “radio” feature, which automatically brings up music from related artists on the desktop. Free, but requires a $9.99 a month subscription, for iPad.
