Social music discovery site iLike made a series of announcements today, most notably full-length song playback through Rhapsody. iLike hooked up with digital music service to allow 25 full-length streams per month for its over 30 million users. After the 25 full streams have been used, users can either sign up the Rhapsody service or return to using the 30-second streams. The full-length streaming playback will soon also be usable for Facebook’s iLike application. iLike also announced a plan to pay out royalties for streams, marking the first time music delivery on social networks has been monetized.
