We all have that friend. The music geek.
I know this person exists because I'm that person. My headphones are always on, I'm constantly recommending music to people (and soliciting recommendations), and I always have music on when I'm around.
I can personally attest to the value of every product on this list, and if you know someone who loves music, any of these gifts will be a home run. 
From helping make music sound better, to helping someone show off and preserve his or her music collection, these 12 items are a music lover's best friend.
