I had never looked at the Pumped Up Kicks lyrics either! it's so funny how for some songs it's so important (see: Someone Like You) and in that track I never bothered as I just like the groove! Harsh lyrics
Born This Way, S&M, Super Bass and Invincible are all decent - there's nothing I don't like but they don't excite me AS much, surprised to see Tinie this high as I know you're not especially a Kelly fan.
Judas, Dance With Me Tonight and On The Floor are great. I agree with you on all three write ups - that Judas was horrid at first, that the 'My Name Is Olly' line is cute, and that J.Lo is still a world great entertainer.
Nobody's Perfect is great, but not as great as her three defining singles for me, this falls into 'the middle' with Who's Laughing for me.
My favourites are definitely The Saturdays, Emeli and Coldplay! What you say about Coldplay is so true. See it live and you'll get it fully!
