Where to put codes for Myspace artists' layouts?

I'm making an artist msypace [for music, I mean] and I really want to put in a good layout but I can't figure out where to put the code?

I've tried every little text area I could but it's not like a normal myspace where you have the "about me" sections and everything.

Help??

Where to put codes for Myspace artists' layouts?

I'm actually not so sure, but just try everywhere.

I haven't ever made an artist one but that's what I would do.
