Try it the other way around without the crutch
Listen to the song or part, learn it in your head, hum it or whistle it as you work out what to play what you have learned. When finished play with the song and look up the tabs/staff and compare what you have with it...you'll surprise yourself how well you can do
Its just like whistling/humming, you hear it you whistle/hum it, but now you hear it, you play it. Because all your life you brain is in contact with your hearing and your vocal chords it knows where all these sounds are and how to produce them. You just have to familiarise yourself with where all the sounds are on a fretboard and relate to them......its the same thing.
