Everyone seems to following be Pandora into the music discovery business these days and Twitter has decided getting into the game by releasing its own music app on Friday. There’s just one catch, however: As AllThingsD writes, Twitter is only making the app accessible to select “influencers” such as Ryan Seacrest before making it available to the non-famous portion of the public. The music app apparently “suggests artists and tracks to users based on a number of personalized signals, including the Twitter accounts a user follows on the microblogging service” and will let users “listen to clips of music from inside the app, using third-party services like iTunes and SoundCloud.” AllThingsD says that the music app will likely be released for all users some time next week.
