Does all electronic music sound the same to you?

Nope. Even one same artist can come up with vastly different stuff. Of course, it would depend on the artist, I can imagine that, like in pop, some people stick to the same formulas and it becomes repetitive... But it depends on the artist...

I'd love to be able to point you to strongbads techno song. in short, theres certainly a formula to most.

no. there are sub-genres i like more than others... like EBM
