Last fall the Free Music Archive, one of my go-to sources of free music for multimedia projects, nearly closed. Fortunately, it was taken over by KitSplit who has kept it running. The Free Music Archive provides free, high-quality, music in a wide range of genres. The content on Free Music Archive is used under various creative commons licenses.
Anyone can download music from FMA for use in podcasts, videos, and other digital presentation formats. Downloading music from FMA does not require any kind of registration. In the following video I demonstrate how to find and download free music from the Free Music Archive.
Applications for Education
FMA can be a good resource for high school students looking for music tracks to use in podcasts and videos.
I am hesitant to use FMA in middle school or elementary school settings because there isn't a way to filter out tracks that might have inappropriate lyrics in them.
The Free Music Archive does offer an FAQ for educators that addresses many questions about use and re-use of audio tracks from the FMA.
