They used to kick major ass, now they suck. I have heard some good things about their newest stuff though.
1994 they were huge. I do remember when the blue album came out. we used to listen to that album constantly. I was in college at the time. their new stuff sucks.
i still really like weezer. i only have the blue album, but have heard songs from pinkerton, and i love those, too. i'll also agree that they've gone downhill, in recent years. i think it's that they lost their original bass player. when they had him, they wrote awesome music (blue album & pinkerton) and now they write crap. maybe it's connected, maybe not, i dunno.
green album and maladroit arent nearly as good as their old stuff (blue and pinkerton). but that's because rivers cuomo was trying to make a better version of pinkerton. they're releasing a new album soon. with any luck it'll be class.
