Rocksmith supports a DLC store that features a growing range of songs as well as future additions such as pedals and amps. Bass guitar functionality was added to the North American version of the game via downloadable content on August 14, 2012. All DLC songs are forward-compatible with Rocksmith 2014, but DLC songs released on or after October 22, 2013 are compatible only with Rocksmith 2014 and will not play on the original version of Rocksmith.
As of 000000002017-03-14-0000March 14, 2017, there are 880 songs and 220 song packs available to download from the Rocksmith store.
Almost all songs are available to buy individually. Songs by the same artist are often available as Song Packs, which include three or more songs, for a discounted price.
