You have no reason not to download this right now.
Oh, you need a reason? You must not have seen Guardians of the Galaxy yet (you should fix that when it hits Google Play Movies, it'll be money well-spent). It's free music (at least in the US). In the meantime, here are just a few of the tracks in Awesome Mix Vol. 1:
- Hooked on a Feeling by Blue Swede
- Fooled Around And Fell in Love by Elvin Bishop
- Come and Get Your Love by Redbone
- Ain't No Mountain High Enough by Marvin Gaye
Seriously. It's free. Just download it now. Hit the preview buttons if you must. But really, just start downloading now.
Thanks to Brandon for the heads up!
