After surpassing 2 million "Likes" on its Rock Band Facebook page, developer Harmonix has loosened its tongue on upcoming DLC for the musical party title.

In the "coming weeks and months," Rock Band 3 will welcome DLC from first-timers Stevie Wonder and Coldplay as well as Rock Band-content alums Breaking Benjamin and Dream Theater.

Teasing the upcoming artists on its official forum, Harmonix did not specific which tracks from the four additions would be available for future purchase. Harmonix did confirm that Coldplay, Stevie Wonder, and Breaking Benjamin will get the full track pack treatment, whereas Dream Theater will add a single track to the game's growing list of downloadable songs.
