have already exported them into Rock Band 2 or 3, was enabled in January 2016. Main setlist Players can play Rock Band alone through a Career mode for lead guitar, drums, and vocals, earning in-game money for their character to purchase new outfits and instruments. Each of the 45 songs has a different difficulty ranking for each instrument part, as well as a total band difficulty. There are a total of nine difficulties, or tiers. In career mode each song in a tier must be successfully completed to move onto the next and unlock the songs in that tier. This tier system is also used for rating the difficulty of the song (the "Band" tier) and its separate instrumental parts for downloadable content even though the songs are not used to unlock new songs in career mode. Once songs are unlocked, they may be played in any mode, including Quickplay, and multiplayer (competitive and co-operative modes) off- or online. Each instrument part in each song can be played at one of four difficulty levels, which include Easy, Medium, Hard, and Expert. Song titles listed in bold utilize master recordings.
