Thanks for the suggestions! Ha! Not so much... My wife's more into punk and rock in general, so she'd be more impressed with me learning more Ramones and Sex Pistols :D I think it's more the slower tempo, and longer notes. A lot of what I like (and what I've been trying to play) is short, fast, repeated notes. Rammstein, Lindemann, the couple of Mars Volta songs I can do decently, etc. But I find that I'm more focused on nailing all the notes than I am on falling into a rhythm, or getting a feeling for why the notes are in the pattern they're in. So I'm kinda getting faster, but not necessarily better, if that makes any sense. The slower tempo songs might help me fix that.
