The addition was announced on May 5, 2008. 1 ( Rock Band Song Pack 1) was released for the Wii and PlayStation 2 on July 15, 2008. With the exception of the AC/DC pack, all songs in each track pack are available as downloadable content in online stores. The initial purpose of the track packs was to allow users of systems without support for downloadable content (PlayStation 2 and originally Wii) to be able to play some of the downloadable tracks. The track packs are fully functional standalone games and do not require separate Rock Band titles to play however, on consoles that support downloadable content, the songs from these packs can be integrated with other Rock Band titles. The packs are developed by Harmonix and Demiurge Studios (earlier packs were developed with Pi Studios), and distributed by MTV Games and Electronic Arts.
Rock Band Track Packs (called Song Packs in Europe and Australia) are a series of supplemental media discs for the Rock Band series of music video games. For downloadable Rock Band songs, see List of downloadable songs for the Rock Band series.
