which license should I supply, if I just want anyone
to be
able to download it freely and - if desired -
edit it, as long as
my name still appears somewhere?
Perhaps you might find this site interesting, regarding licensing
issues.

Personally, I find the Creative Commons licences flexible, but far too
wordy. They are more like a contract, a EULA, or the GNU GPL than
existing music licences. Almost no-one reads the GPL end to end -
that's why so many people don't understand it.
Look at any CD package; the licences tend to be about one paragraph
long, and could be edited down to just one word - DON'T. A really
good free music licence would be just as succinct.
If you want to allow derivative versions, have a look at the bLiP
licence. Second item down on:
