Rock Band 4 has a couple of U2 songs and there is nothing you can do about it.
Yes, in an ode to Apple, you'll get these songs included as part of the package, although the inclusion of "I Will Follow" and "Cedarwood Road," is not likely to upset too many people, not like when Apple forced iPhone users to have the latter in their music library.
Rock Band 4 includes music by Aerosmith, Foo Fighters, Van Halen and more. It also works with the 1500 tracks available for download on the Rock Band Music Store and if you have songs from previous discs, then it'll work with them too. We're happy to see it back. Are you?
