Instead of giving up, listen to it. Yes, I know you have listened otherwise why are you trying to learn it but there are many types of listening. Here are a few quick suggestions of when, where, and how to listen.
Listen while cooking: When your hands are busy your mind has the ability to focus and relax at the same time.
Listen while playing: with your kids, board games, hobbies, video games, or whatever you do to relax. You will be surprised what you will hear the next time you do a focused listening.
Listen while driving: Perfect time to absorb music without distraction as long as you still drive safely.
These are just a few suggestions. Post or comment on fb some you think of.
