Too late.l, I used the last 5 minutes to do it already. :)
I knew several Taylor Swift songs from the radio, but didn't think more of them but "the usual generic pop music" that normally leads to me changing the station immediatly (I expected this). I don't think I will recognize her the next time I hear her.
I also knew some Kanye West songs and I even liked some of them (I honestly didn't expect this). I somehow don't want to like his music though, saw too much about him on Twitter and here).
