With the release of "Pitch Perfect 3" edging closer every day, we thought it was a perfect time to bring you our #Top10 a cappella covers of movie themes!

Pitch Perfect 2 Opening

10. Pirates of the Caribbean by Live Voices

Hailing from the Ural State Conservatory in Russia, this quintet is giving away all kinds of goodies on its Patreon page.

9. Back To The Future by Marco Arata

Although there are 27 voices on this track, all of them are Marco. You can find more from this One Man Orchestra here.

8. Jurassic Park by The Warp Zone f/ Peter Hollens

The Warp Zone is a nerd sketch comedy, gaming, and music video channel brought to you by five lifelong friends. If you made it this far, you'll certainly enjoy their other a cappella videos (of which there are many)!

7. Evolution of Bollywood Music by Penn Masala

Known as "the world's first South Asian a cappella group," Penn Masala hails from the University of Pennsylvania.

6. Psycho by Petra Haden

Petra Haden's intense attention to detail in her a cappella covers is incredible, and if you don't know her, you should now!

5. Harry Potter (Hedwig's Theme) by Overboard

Overboard took it upon themselves to release a new track every week for a year in an effort to get better at producing a cappella. Not a bad idea at all!

4. Mark Mulholland's One Man Matrix

Mark Mulholland recreated the entire iconic "Lobby Scene" from the Matrix complete with score, sound effects, and much more!

3. Lord of the Rings (Misty Mountains) by Peter Hollens f/ Tim Foust of Home Free

Peter Hollens and Tim Foust. Need we say any more?!

2. John Williams is the Man by moosebutter

This is technically a "cover" of Corey Vidal's legendary video of the same piece. You may not know that Corey's original video was actually a lip sync to moosebutter's original version.

1. Ghostbusters by Pentatonix

One of the greatest movie themes sung by the one of the world's greatest groups. Shout out to Chadderdon Videos for making this video.
