That would be really killer to get a Dos tune on the sampler. I submitted a song, pretty much, here's the deal... (It's all in the link Mr. Paul provided)
You fill out this Limited Use Agreement:
http://www.talkbass.com/samplercd/Li...Agreement.html
Then mail it/fax it
Then, You go to the song submission thread:
http://www.talkbass.com/forum/showth...82#post1335782
And post the info on the song
Then you'll get a PM in a while, and they'll give you an upload link. Then your all set...
Uh, It sounds more complicated than it really is.

I really hope you get a song on. :bassists:
