When I first started playing, I would get up early and turn on the vh1 classic morning video block, and try to play along. Now I was quite terrible for a few months, but I started to improve, picking up on common chord changes and harmonic motions, and how the bassline fit into these tunes. This was quite good for my ear training, and also taught me a little about theory.
just my experience, ymmv. I always enjoy playing along to something, be it a cd or in a live band setting, and feel this is a pretty sustainable skill to have. Btw... Nice choice in the dyna, OP
