This is a nice version of What is love. You didn't use high programs or other? What ever! It could be nice without them too. :) I like to hear this version of What is Love. :P It's many time's better them my version. (I don't uploaded yet)
Everything you added doesn't mix well with the original tune, you should of changed up the instruments instead of leaving them as MIDI instruments.
In short, crap.
Your opinion, to be honest I don't have an expensive or high tech programme.
You gave constructive critisicism which i'm gratefull for, but you'd could've be a bit less of a cunt at the end
..Thanks for the review
