Since it was a cover, I listened to both that and the original to give it a fair judgement.
Pros: The instrumentals are great and fits a song like this. The lyrics are powerful and empowering, so props to the original writer for it. The guitar riffs and solos are awesome, and I think it's a better song than the original.
Cons: The vocals and the singing. They're weak and underwhelming and should have more energy and passion, especially if you consider the subject matter of the song. Going back to the writing, the bridge before the solo was pretty narmy, which took the mood off a bit.
Overall, really great song that it trumps over the original.
