Welcome to Music Mondays (er, Wednesday?) -- our weekly Spotify playlist with the music we're currently obsessing over, locally and beyond.

Okay, okay, it's not Monday, BUT we're late for a very good reason -- the entire lineup for 2012's Underground Music Showcase has finally been revealed! And for playlist number four, we've put together a mix of songs from the artists (both local and national that have songs on Spotify) who are confirmed to be playing at this year's UMS fest.

For a complete list of all bands playing at UMS, click here.

Turn it up, subscribe, enjoy, let us know what you think in the comments below and stay tuned for another installment next Monday!

And in case you missed them, here are our previous Spotify playlists:
