Hey, I've just recently found Good Riddance through some random means and considering I don't really listen to punk, I don't know any similar bands. What I'm looking for is more of the sound and if possible, particularly similar vocals. The lyrics don't have to be similar as in the kind of straightedge lyrics, if that makes sense. Thanks for the help and all in advance.

Oh and if this is a really broad kind of question, sorry about it, just throw whatever you can at me.
