I love Ke$ha! The thing with her songs are she's saying what she feels. All her songs are based on her life. I hate the singers that think they are really good because they don't swear. When Ke$ha swears, I know she's saying what she feels.
I've heard these ones:
TiK ToK
Backstabber
Kiss 'N' Tell
Your Love is My Drug
D-I-N-O-S-A-U-R
Dirty Picture
Boom Boom Bang
Blah Blah Blah
Animal
Paris Hilton's Closet
Boots & Boys
Blind
Dancing With Tears in My Eyes
Stephen
Party At a Rich Dude's House
My faves are Boom Boom Bang, Backstabber, Tik Tok and Stephen. It's funny, when I walk to the bustop, I mouth the words to all the songs, so I look like I am singing away to myself. The first song on my playlist is Backstabber, so now I know every word to that song. It's quite funny, when it comes on, I automatically start singing.
