Two albums I have listened to endlessly and am still into after months and months are Jessica Lea Mayfield's With Blasphemy So Heartfelt and Mount Eerie's Lost Wisdom. The former is an 18 year old bluegrass/country singer songwriter with strong 'indie' leanings and the latter is just the coolest lo-fi folk musician ever to come out of Anacortes, Washington.
I was also digging on the new Nada Surf (yeah, Nada Surf) and Crystal Castles (hipster electronica). Other then that there has been a lot of good/ok albums that I can't remember off the top of my head.
Oh and as long as we're nominating albums from 2007 (see: In Rainbows) I'd like to mention the National's Boxer album. :-)
Here is a video of Ms. Mayfield:
