In the image above it's 'Falling to the Earth', but it's almost every single track in the collection. Other very notable tracks are: Rex Furry's Secret Base (

), Vehicle Robbery (

), Time Trail Free Run (

). There are a few exceptions to the rule here though: Inside The Dojo (

) and Inside the Police Station (

) are excellent.
It's a great soundtrack for sure, but this rip is quite litterly headache inducing :(
After listening to some of the examples you gave, certain sections did sound a little wonky while the rest of track was quite bearable. I didn't have an issue listening to them full-blast (with the volume turned all the way up in foobar), at least not all the way through. But who knows, maybe my hearing is more attuned to this degree of sound, which doesn't mean yours is bad or anything, and I do apologize for the wonkiness in the tracks.
The upload came from this playlist (
https://www.youtube.com/playlist?list=PL2XjmdkuVL-27MA37lIvKLfOHG7ANHoXe) that was linked inside the Lego City Undercover request thread. Feel free to compare the frequency between both collections, and if mine sounds worse then I'll own up to it. ;P
And just for the sake of it, has anyone else had this problem?
