I think it sounds more overproduced than the final version.
The way the backing vocals and the lead vocals are mixed together makes it sound like a technique that should be used on Britney's records or Hillary Duff's. The accoustic part is good but it doesn't flow right with the song, it just sounds like they're trying to recreate the Undivided ending part. The solo is wayy better now and I miss the last part to much "When the world keeps trying to drag me down..."
oohh and the lyrics are much better now, both on the second verse and on the chorus.
