I added 567 tracks to my collection by my count (it's a complicated story but I may be off by one or two because of duplicates), compared to 271 last year. Christmas music comprised 26 of those 567 songs. There were a lot of downloads of individual songs, as well as the first song in my next project - converting my vinyl collection to mp3 format. I have maybe a few dozen 45s and many more 12-inch dance remixes, probably in the hundreds. I'm so excited about this.
Beyond that, I got some free downloaded samplers and mixtapes (which is such an odd term to use for mp3 downloads, but...):
Will Sheridan – G.I.A.N.T. Sampler
DJ ShyBoy presents the RuPaul Mixtape (RuPaul songs mashed up with other songs)
DJ Jazzy Jeff and Mick Boogie – Summertime 2: The Mixtape
DJ Jazzy Jeff and Mick Boogie – Summertime 3: The Mixtape
Dangerous Muse – Red
Slaves to the Rhythm – Pride 2011 Sampler
And then there were the albums that were released prior to 2012:
Kelly Clarkson – Stronger
Discovery – LP
Ricky Martin – Ricky Martin
David Guetta – Nothing But The Beat
Jody Watley – Midnight Lounge
Paul McCartney – All The Best
Donna Summer – She Works Hard For The Money
Elton John – Rocket Man - Number Ones
Steely Dan – The Definitive Collection
The Gap Band – The 12” Collection and More
Nona Hendryx – Nona (as I mentioned here, the first full-length album I transferred from vinyl to mp3)
Katy Perry – Teenage Dream-The Complete Confection (this is the re-released version with bonus tracks -- the original was out in 2010 so I don't feel right counting it as a 2012 album)
