Sara Bareilles - King of Anything
I paraphrase Ms. Bareilles, but she shared that this song was about people who should "mind their own f*cking business." Hilarious how upbeat and catchy it is too!
Brooke Fraser - Shadowfeet
This song comes off of her second album "Albertine", I saw Brooke Fraser perform live a few years back at Berklee College of Music. You may know her as a worship leader at Hillsong and the song "Hosanna", but she has some excellent solo albums I would highly recommend checking out. She falls roughly into the Pop/Folk genre.
Katy Perry - Teenage Dream
OK, I'll admit that I just can't resist a good pop song. This song will get stuck in my head for days and was covered by an all-male a cappella group in last week's episode of "Glee". Yea, a little weird for guys to sing it, but a nice arrangement nonetheless.
