I don't really know what to put in a vocal review, but seriously, Brent Smith, the lead singer, has the most simplistic singing style, which makes it easy to hit.
Being easy to hit, I find it a good chart, because there aren't any bullshit way-off charts like some Alice in Chains songs were.
If you ever did the vocals to Blurry-Puddle of Mudd, or any Breaking Benjamin song, and did good on any of them, you'll be able to do good on this song.
The song doesn't totally suck, so you'll most likely find yourself enjoying the song enough to actually have you dance around a little bit.
Chart-wise, the song is good, (solo vocals) and for the amount of fun, it really just depends on how you feel about that song.
