Well, I see no one's really bitten yet, but I think this is a cool idea - like a vocal album themed around new collaborations. Even if the album doesn't materialize, I think the site could use more vocal collaborations. I personally have heard some nice remixes on this site that I would love to rap over. Here are some ideas (although I'd undoubtedly need to get in touch with the original remixer):
Elegy of the Solipsist (http://ocremix.org/remix/OCR02381/) - I would rap on this in a heartbeat; I've actually thought about it. I'm thinking of a playful but bittersweet love song, Link to Marin, about how he loves her but ultimately knows (spoilers) she isn't real and will disappear if he awakens the Wind Fish
The Life and Death of the Mario Brothers (http://ocremix.org/remix/OCR02062/) - sick beat, this would be standard rap braggadocio
Insecta Robotica (
) - no ideas, but I've always liked this remix, nice beat(Additionally, I would be interested in writing a reggae song about Mario, although I can't think of an existing remix that would work. If someone could work on a Super Mario Sunshine beat with me, I have some lyrics for that as well.)
Also, just a thought: I don't know, but it seems to me that writers couldn't just write lyrics and give times when to deliver them - there's a lot in the delivery that's hard to convey in writing. Perhaps the writers could do their own shitty performance and send the audio to the real singer, who can get the feeling from the audio and then blow it away?
