ok. as far as at least that second link goes, we CAN NOT remix those recordings. He is quick to point that out. Heres the thing about music.
Two things get copyrighted.
1. The song, i.e. the melody and the lyrics can be copyrighted. chord progressions can not. titles can not.
2. The published recording is ALSO separately its own copyright. thusly, even if a song is public domain, a persons recording of it is not.
seems strange right. but the guy does specify that his files on that site are not public domain.
so. i encourage you all to record your own versions of these songs so that we CAN remix them.
but uh... dont remix that guys files.
hope that helps!
