do you suggest any bands?

I'd check out Mr.SuicideSheep's or Proximity's Youtube channels for collections of tech-y/dub songs. I'm bad with genres, but their stuff's good and I'm sure you like it.

If you like jpop then you should totally check out Myname! - http://www.youtube.com/watch?v=s0nuGcumWMA


and listen to Dash Berlin and Cosmic Gate too cuz you seem like you enjoy electronic stuff :D

If you make Nightcore, I have some nice Nightcore channels.

Gorillaz sounds right up your alley. They have a perfect blend of techno and alternative rock, along with great lyrics.

Fugazi
Only Living Witness
Crystal Method
Lords of Acid
