I'm sure in the next 6 months I'll hear a bunch of great tunes that were released in 2013, but anyway... here's a loose list of some things I really enjoyed this year.
Oscar Key Sung - 'It's Coming' (Australia)
Probably the song I listened to most this year? I dunno if that's true, but. Slinky Australian R&B.
This was free on his Bandcamp, but got pulled a few months after release, so I guess it's been picked up by some label who doesn't like that approach.
