I was wondering if you could use a program like audacity or the like to import an mp3, and isolate a track (like a guitar or bass line) to better learn the part in the song.
I have a decent ear, however there always seems to be something lost in translation when I learn a song completely by ear (particularly jazzy chords), and it would be a fantastic asset to be able to hear a song literally one track at a time, as fast or slow as I need. Thanks
