It seems like making a pre-order on Rock Band 4 to Xbox One just might be a good idea. PS4 players will get ten extra songs included with a digital pre-order, but for Xbox One there will be a total of 12 bonus tracks, according to Rock Band Aide. Maybe the extra two bonus tracks are compensation for having to pick up an adaptor to play with old instruments on Xbox One.
We'd like to make special mention of a couple of these tracks. One of them is the highly original band Babymetal and their hit Gimme Chocolate!!, and the other one is no other than "Weird Al" Yankovic, with My Own Eyes. To give you an idea of the range of the Xbox One exclusives there are also tracks from Marilyn Manson, Interpol, Earth, Wind and Fire, and Mastodon.
Head over to Xbox.com for the full list. We assume these bonus songs will also be available as separate purchases on PlayStation 4, sooner or later.
