It's funny this should be the first commercial song review. When I first heard this song it was someone else singing it, and I thought to myself "that's a good song".
But the more I listened to it, the less I liked it.
Here's what I think. It's a very strong melody and harmony. And some of the lyrics are pretty good. But it reeks of "professional songwriting". In other words I find it a bit contrived and slightly cynical. The space this song has for authentic emotional communication has been compromised slightly because one eye is firmly on the commercial appeal.
The mid 8 sticks out a bit too much for me - it doesn't necessarily sound like the same song, even though it "fits" technically.
If you are really picky, the chorus lyrics aren't really cutting it. Leaving scars, catch a cold. I can think of better punishments to be honest.
But like so much pop music, this one's all about the tune. And it's a good tune. Not strictly my cup of tea, but it's very singable. I don't like the middle 8 - and it reminds me of the mid 8 of "don't speak" by No doubt (a much better song than this in my opinion).
Keep the commercial song reviews coming - I think this is a really worthwhile exercise.
