One way to slice it is to use one for 'songs' from my actual CDs, just to post them SOMEWHERE so I don't have to send MP3s from MY email when I want to pitch or share them.
And use the other one to post/share my (instrumental) film music.
There's by now zillions of these sites - how many can one possibly manage, or need to?
How is somebody else doing it?
A fiver for your thoughts...
