I have a shit ton more, tell me what you think so far.
kawabunga on Soundcloud and look for Sei Mutsuki, Intero, Skittlegirl Sound, Andy hiroyuki, Traceon, etc even.
Surf through the related tracks for some of those artists on Soundcloud, you'll thank me later! :D

try looking up guys like Modern Talking, Rick Astley (Yes you got rick rolled), Aha - Take on Me, Depeche mode etc.
Or check my SoundClou- jk jk <_< >_>
