I hate it. So many of the artists I liked to check out have all but been lost because of MP3.com implimenting their three song rule a few monthes back. Those affected include yours truly, and Guru Zim!
There's not much I can do to fix it... if I DO want to have all my songs up, it'll cost me about 10 bucks a month, and since I don't have any sort of music budget whatsoever, I'm not about to pay it.
For a site that promotes free distribution of music, they've really became stiff lately.
I think I've still got my MP3.com site floating around, but I haven't used it in ages because of the state that MP3.com has fallen in to. That, and I found that I did have a budget to pay for hosting for my music. You could open up a 2nd MP3.com account (if they still let you do that), put up three more songs, and link the two pages together.
If nothing else, you could always just get yourself an Angelfire site, since they give you 20MB of space and are pretty lax about checking for MP3s. Although, if they're yours (which I'd imagine they are), I don't think it should be a problem. Plus, it's free. Granted, you lose the community vibe of MP3.com, but the last time I checked the MP3.com boards, it was more of a shillfest than an actual community.
Basically, what Mr. Heel II said. I suppose you may be able to record right from the turntable, if it has RCA jacks and you have an RCA -> 1/8" phono adapter. However, I'd suggest using a WAV editing program like Cool Edit.
