excellent. im not much of a fan of covers, but that doesn't mean this isn't still excellent :p
Sounds rather charming and like it would be good credits for a tribute movie as well since it sounds similar to the original minus the overly pumped up combination of the synths and bass working together.
The synth here is really nice and kind of makes me think that it is partly mixed with a guitar to produce that rhythm that keeps on going. Then the bass helps the song keep going in the back and I like how it sounds more like an atmospheric bass sound. Also kind of funny how if one pays attention to the original and this cover it is really just a long beautiful melody of all the songs in the movie put into one tune.
The drums also sound really nice here and greatly done for simplicity. Liked how you added a filter to them for a cool effect. Great beat.
Overall, awesome cover.
Please contact me if you would like to use this in a project. We can discuss the details.
