I'm not much for Weezer but I love me some Ryan Adams. Apparently Weezer front man Rivers Cuomo told MTV "I just wrote a song with Ryan Adams. Not Bryan, Ryan. It's a very stirring and emotional and powerful song. He was really inspiring to work with. ... He has a lot of wild and crazy energy. It's gonna be on the record. He plays lead guitar on it, but it will be on the record, for sure."
Hopefully we get some nasty guitar work from Mr. David Ryan Adams on this.
