I listened to Thrill Ni@@as.
I noticed clipping in the beat track and some sort of slow flanging or comb filtering on the vocal. The vocal also seemed to overpower the beat track.
I liked the beat well enough.
One other suggestion/comment - when someone else contributes a vocal to a track that's already recorded, you can get the two elements to sound as though they were recorded at the same time by adding a slight amount of reverb to the final mix.
