One thing I also will post a bunch, besides talk about football or solar, is music. Particularly electronic music. I used to post over at loudmusicallday.com with some friends but that kind of died off and I discover too much good music to not share.
Below are some good covers I've found recently:
Thief - Cry Me a River
Cassie Steele - Sex and Candy
Animal-Music - Mr. Brightside
