The Rock Band series of music video games supports downloadable songs for the Xbox 360, PlayStation 3, and Wii versions through the consoles' respective online services. Users can download songs on a track-by-track basis, with many of the tracks also offered as part of a "song pack" or complete album at a discounted rate. These packs are available for the Wii only on Rock Band 3. Most downloadable songs are playable within every game mode, including the Band World Tour career mode. All downloadable songs released before October 26, 2010 are cross-compatible between Rock Band, Rock Band 2 and Rock Band 3, while those after only work with Rock Band 3. Certain songs deemed "suitable for all ages" by Harmonix are also available for use in Lego Rock Band.
