Putting downloads on your website for paying is not trivial though.
It's easy to provide a file for download, but it's much harder for a site to know who's paid and who hasn't, reliably and without inconvenience for the user or possibility of abuse.

The cheaper web hosting packages don't even let you do server side scripting to start with...

I don't know. Maybe I'll try creating a page with a few songs and tunes at £1.00 a track and see what happens.
I'll let you know if I get rich on it... (don't hold your breath)
