The real fun in this game comes from messing around in Freestyle mode and combining different songs, especially with the thousands of custom songs people have modded into the game. You can make combinations that sound surprisingly great, or you can put the vocals of Bring Me to Life on top of the instrumental of Call Me Maybe. Unfortunately, in order to learn about all the different things you can do and unlock new things, you need to play the campaign mode, every level of which drags on for far too long.
