does anyone know any good software or something so that i can transcribe songs easier? something can separate/EQ each instrument is what i am looking for.
I'm afraid there's no such thing, unless you have all the separate tracks to begin with.

That being said, Amazing Slow Downer can at least eliminate the lead track most of the time, at least when it's in the center of the stereo image. Of course it can also slow music down: http://www.ronimusic.com/slowdown.htm
