The Charli XCX track is indeed amazing. It's the most current sounding track so far. The thing that sells it to me is that it sounds like a bonus track off of True Romance. I really want Charli to go back to that sound. Listening to the HQ iTunes file of 'Tom's Diner' it sounds much better to these ears, but that's probably also because I've only hear the MQ rip before. Kelis' vocals sound really shit. The auto-tune is not good at all, on purpose or not.
