There are quite a few sites where you can find completely free music to use in your YouTube videos, indie films, and more. And just because they're free doesn't mean they're terrible! You'll just have to dig through large catalogs of music to find what works for you.

1. Mobygratis

Mobygratis is a site created by the recording artist himself, Moby. With over 150 of Moby's tracks available for noncommercial projects by "independent and non-profit filmmakers, film students, and anyone in need of free music for their independent, non-profit film, video, or short," there's a lot to choose from.

You can search for music by album, tempo, type, mood, and genre. You're going to have to sign up for a free account to download music from Mobygratis.

2. Musopen

Classical music is an obvious choice for those looking for free music, but that doesn't mean it's all copyright free. Musopen makes it much easier to figure out what classical music is available under a creative commons license.

Chopin, Beethoven, and Mozart are among the popular composers whose work is available on Musopen, but you can also find music by plenty of lesser known composers that will set you apart.

Browse by composer, instrument, period, form, or performer to find the perfect song for your next video. Be sure to look at the creative commons license as not all of the music is available for commercial use. You'll need to sign up for a free account to download music from Musopen.

3. Bensound

Bensound is a solid site with plenty of creative commons music to choose from. All the music comes courtesy of Benjamin Tissot, a musician based in France. You can browse the music by genre and unlike the other sites listed here, can download music from the site without having to create an account.

You can use the music for free in online videos, websites, and animations, as long as you credit the site. If you prefer not to, you can purchase an extended license.
