You listen to a song, now ho do you figure out what scale it is in?
It never seems to be a good answer to this question.
I know i have to know what genre the song is, thats for sure.
I know that i have to know the minor,major and pentatonic scales too.
Those 2 things i know but i dont know HOW to FIGURE OUT what key and scale it is in.

Please someone help me out of this.

that's nonsense tyhe genre doesn't matter, scales however do but the most important part is hearing. it's not difficult to divide(sorry for the crappy english) a prhygian and a spanish scale from eachother.
just listne and listen a lot, you can't expect to have a song figured out entirely, on just one day. that takes a lot of practice and experience
