stock music sites

Hiya- I sell some work locally to businesses (for jingles) and lo budget filmmakers- A client recently showed me a few sites he uses for stock music- as an artist, you set up a selling account and post your stuff up for sale- the site gets a %- A guy a while back put some of my stuff on this site http://matchlessmusic.net/artists/41, but I was thinking about setting up shop on one of these bigger ones- here’s what he referred me to: http://www.stockmusicsite.com/ , http://www.stockmusic.net/ , and http://www.audionetwork.com/
Anyone here had experience with any of these?

thanks

Unfortunately not.

However, I’d add bandcamp to this list.

You mean Royalty free music libraries.
i am working with this one. Royalty free music at http://www.themusicase.com

you can upload your stuff there and they will include it to their library.
Here is the link http://www.themusicase.com/texts/composers.html

You can also use royalty free music term on google instead of stock music.

I use archive.org for uploading my sound demos. You can either copyright your material, or do what I do and list it under public domain. Either way, I’m not sure if you can get royalties from archive.org.
