One thing that helps me is to keep a note pad handy and make notes of the songs I hear. If I happen to catch the title and artist of those songs, I find that I can find them later on LW. For most of my life, I've heard numerous songs that I could tell you some of how they went, but I couldn't tell you the title or artist (since I either forgot the names, or I never got them to begin with). So keeping a note pad handy has helped me remember.
