Royalty free electronic music?

Try Jamendo, all the music is free to download and is released under Creative Commons and Libre Art Licenses. There’s some reasonable stuff on here, but mostly amateur and unsigned artists.

Try:

and

both have CC and royalty-free options for purchase

Podsafe music refers to music specifically for podcasters or broadcasters. The music is licensed in such a way that podcasters can purchase a license to include the music in a podcast without incurring additional fees or expenses. In order to use traditional music that is heard on the radio in a podcast, podcasters may have to pay royalties for each time the song is played. Some music files licensed under public domain or creative commons are exempt from royalties and these songs are available for use in a podcast, but generally when searching for music to include in a podcast it is probably best to stick with music that is specifically designated as “podsafe”.
