I think people here have noticed that it would be very difficult to host a place at mudcat with all mp3 that would com up.Like Nick mentioned ,I found a place ( sonicgarden.com), where they can host a limited number of songs(I myself have put a few there in genre blues ,
subgenre acoustic, as guitarjoe).Maybe this could be a way for the new musicians to show their songs there at mudcat, by putting available the links for the sites.
