Every morning, right after we figure out where we are and piece together the events of the previous evening, Diffuser.fm gives away a free MP3. Today, it might be brooding alt-country, while tomorrow might bring thumping indie disco, earnest '90s-style emo or socially conscious hip-hop. There's no telling what we might throw you, and now, we’re asking you to tell us what you like best and vote in our Crucial Cut of the Month contest. It’s a chance to select your favorite free MP3 of the last month and help your favorite emerging acts get a little digital love.

Here’s how it works: On the first of every month, we post a poll like the one below. Listed here is every song we gave away during September 2013. You have all of October to cast your ballots, and on Nov. 1 — the day we roll out the next poll — we’ll announce the top vote-getter. What do they win? Diffuser.fm can't promise fame or fortune, but we can and will profile each Crucial Cut winner with a Q&A feature, and throughout the month, we’ll promote their music on our homepage and via social networks. Click here to read the piece we did on last month’s winner, Black Wing Halo.

Check out the full list of September 2013 downloads below. Click on the artists’ names to view their individual posts, read their back-stories and, most importantly, listen to their songs. Voting ends at 11:59PM EST on Oct. 31. Good luck to all the artists.
