Kelly Clarkson - Since you've been gone
KT Tunstall - Black Horse and the Cherry Tree
I don't own either of these songs, hell I don't even like them very much. KT has a cheery riff (with me everybody..."whoo oo"..."whoo oo") and Kelly is very angsty ("grrr") but I didn't hear them on the radio or on the tv or anything. How did they get in my head overnight and what does it mean?!
