I'm happy to share with you some more free music from Google Play: 25 Years of Merge Records! It's a great sampling of indie music.
There's Arcade Fire, Superchunk, Neutral Milk Hotel, Spoon, She & Him...really cool stuff to be had! Definitely take a look if you love free independent (and legal!) music!
Google has changed up the format of downloading a bit, so I would recommend opening up new tabs for each song (middle click with your mouse). Although you can do it other ways, I think this is the most efficient.
Let me know your favorite song!
