I don't have the whole cd, but I have a few of the singles they released. My room mates actually said they didn't like their old stuff, but they absolutely love their new stuff. They sound like a more matured band, rather than that little boy band they used to sound like! I can't wait to get the new cd, but I'm probably going to wait until after christmas. I also love the Beat It remake by fall out boy.
I would say you'd probably like the newer stuff, but give it a listen on youtube. I'm pretty sure most of the songs can be listened to through you tube.
