I've started to do the same Alex on non-multitrack versions with my guitar volume much louder over the music and it's really helped me to improve a lot by actually hearing what I'm playing and trying to make it sound good and musical, rather than just hitting the notes on time like a rhythm game. But by just turning the guitar volume up over a standard track, I sometimes find it's difficult to keep the rhythm as my guitar sound drowns out the bass / drums too much on certain songs and I struggle to keep the groove, and then I end up playing by eye, using the note highway and it defeats some of the benefit of trying to listen to my guitar sound and play by ear. Now that I've just discovered the multitracks I think they're amazing, to get the best of both! It's so useful to be able to hear what I'm playing properly, but also still being able to play within rocksmith with the speed up / slow down features etc. I've noticed though that many multi-track versions of the CDLC are down though, they seem to be on a Mega account that has been deleted. Most of the Metallica ones anyway, and some others. Also It would be cool if there was a search option for Multi-tracks / Stems or something, seems like right now I think it depends on the authors all labelling the same way and I wasn't sure if I was finding all of them.
