I need a new music obsession?

[Gemma]

I used to love Lady GaGa in a really obsessive way LOL, but then I found out some horrid stuff about her and stopped liking her. Since then I've had a kind of "gap in my heart" (that sounds so dramatic haha) and I just feel like I need a new music obsession.
What are some good bands and stuff?
Bands or singers that I can become FULLY obsessed with, and I mean obsessed. Join their twitter hashtag conversations, reblog a bazillion photos of them on tumblr, cry when I listen to their songs, relate to their songs etc.
It'd also be nice if their music had some kind of meaning, or a fan base so I could talk to other fans.
