Looking for a source for royalty-free music for use in "Music On Hold" (when you place callers phoning into your business on hold - any ideas for low-cost / no-cost options?

Here is a source for classical.

Audionautix, Dan-O, Incompetech, and Jamendo spring to mind.

I think these qualify. Beware though, it’s run by Microsoft.

Being able to download a song for free does not mean that you can use it for commercial purposes. Those are two separate things, and if neodk runs into any legal trouble you need to take care of every fee and fine that occurs because of your craptastic answer.

I have no idea how it’s done, but several offices that I call actually have a local radio station playing on the phone when they put me on hold. I imagine there’d be an investment in some kind of equipment to make that possible, but no fees for the music. The downside is that callers hear commercials, DJ banter, and weather reports in addition to the music.
