No doubt he does a fantastic job on all the covers but i'd be lying if I said I didn't get a bit fatigued listening to the entire thing at once since I only truly understand his English lyrics. I do wish they would have made an extended version of the soundtrack where it includes a lot more then just 5 of his tracks though as that's too far in the other direction. That's mostly just a personal problem though since I do not understand Portuguese and it says a lot that I can still love the covers so much just a bit difficult at times to last for the full 14 covers.
Saying that, i'd still also buy a full official version of just his tracks but prefer to have other tracks from the movie mixed in.
