Don't get me started about Songs from the Black Hole. Which "Weezer board" did you get that from? There's lots of them.
SFTBH has never fully been released - they are demos that never were finished, some songs I dont think were even recorded but a lot of the songs actually turned into songs on Pinkerton (like Tired of Sex) or B-sides (like I Just Threw Out The Love of My Dreams which is sung by Rachel Haden who now plays with the Rentals - the original =w= bassist Matt Sharps solo band and they played that song live last summer it was great!). Over the past 2 years more and more songs were released from it in a variety of ways - including the long awaited Superfriend and Who You Calling Bitch? on Rivers' Alone demo CD.
Blast Off! is my favorite, and actually it's one of my favorite =w= songs ever. About 4 years ago maybe 6, someone hacked into Rivers' computer and got a hold of the song and leaked it on the web. Weezer.com responded to it by actually posting it for download. it was insane!
I know far too much about Weezer.
