Spend entire days listening to nothing but Bach and Coltrane's discography. Train yourself to hear the mechanics of music. You'll hear things you didn't before, and enjoy things you couldn't before.

Then train yourself to hear other musical languages, like maqams and ragas. If you've run out of music to blow your mind at 23, you haven't looked very hard. Two mind bending, stuff of legend records came out this year alone, "Aethiopes" and "Thisness".
