If you can slow the song down, it will definitely help. There is an interesting tool. I don't think it's worth the money, but then I don't have your problem.

If I were you, I would just play the songs that I can get tabs and info on and train you ear. You will find that it's not really all that hard. You just have to know your guitar and know the song (melody, beat, key, etc.). You can also, get an instructor to teach you everything you can handle including certain songs.
Good luck!
