My 11 most played artists in 2009, according to last.fm:
1 Pet Shop Boys // Fueled by Yes, its b-sides and the Christmas EP.
2 Lady GaGa
3 Erasure // I didn't get the anniversary rerelease of The Innocents, but they made it near the top anyway.
4 Alanis Morissette // Producer Guy Sigsworth helps revitalize Morissette on Flavors of Entanglement. It's no doubt his influence that sees some of her denser rock pieces replaced by the toe-tapping likes of "Giggling Again for no Reason."
5 Madonna // She can't buy a hit these days, but "Celebration" and "Revolver" were welcome if not mind-blowing offerings.
6 Lily Allen // Allen didn't take hold the first time around, but second album It's Not Me, It's You is stuffed with the thoughtful ("The Fear") and hilarious ("F*ck You," "It's Not Fair"), all of it deadly catchy.
7 Tori Amos // My interest in some of Tori's newer material has cooled, but Abnormally Attracted to Sin, an impressively cohesive piece considering its 17-song length, provided a welcome thaw.
8 Annie // Had the really good Don't Stop appeared earlier in the year, Annie likely would have made the top three. "Hey Annie" is hypnotic, and the Berlin Breakdown Version of "Anthonio" is a fun throwback to '80s balladry.
9 La Roux // I haven't listened to the album as a whole a great deal, obsessing instead over individual tracks such as the sublime "Fascination."
10 The Bird and the Bee // Their second full-length, Ray Guns Are not Just the Future, which included a couple of previously released strong tracks amongst the new songs, failed to click with me (an ode to David Lee Roth — seriously, TBATB?), but standout songs "Love Letter from Japan" and "My Love" helped TBATB just squeeze into the top 10.
11 Michael Jackson // The list goes to 11 for the sole purpose of a nod to MJ, who fell so sharply off the radar in the late '90s and all of the 'oos that he had become out of sight, out of mind. It's sad that it took his death to get us all to rediscover the magic. The soothing "Human Nature" emerged as the song I listened to most following his death.
