Guys, this is my first ever work done with ableton, it's a mashup of Mr.Brightside (the killers) With Nillionaire (alesso), excuse the volume ups and downs it has, i haven't mastered it yet.

I need to spice it up, add some cool effects to the vocals, bringing them with small loops, not like actually slamming them in.
Give me some suggestions, does it actually sound good, vocals go good with this song?
