Query: Goo Goo Dolls - quality stuff!

I think the Goo Goo Dolls are great!!! John Rzeznik has aUNBELIEVEABLE voice (he should sing all the songs, no question) and Ithink he's really innovative with all the crazy tunings he uses on guitar (I saw the GGD in Baltimore, and he has a rack of guitars behind him, he's constantly changing, he was even changing during songs!). The songs, Bullet Proof and Acoustic #3 (this song should be longer) are really good, and you can't lose with Iris, Black Balloon, Dizzy, and Slide (I never get tired of them). All in all, a great album, I just can't wait to see what Johnny comes out with next!
