Various songs on Rocksmith. I pretty much have Knights of Cydonia down so I'm happy with that. I prefer playing along with a song than a backing track and just noodling (though I do that as well). So Rocksmith is pretty fun for me given my lack of confidence, lack of time and lack of anyone to play with
I might spring for some extra DLC the idea of trying to play some Disturbed songs interests me...though I never have before
One thing over and over, getting a small fragment of the diminished whole/half scale into my playing so it's "natural" - namely, playing over a dominant chord with the blues scale (mix of major and minor)but dropping in a H/W/H sequence going b5, #5 and Maj6. Pretty cool sound.
