People still use the radio a lot it seems, particularly in commutes to work. Again just aren't willing to set up month's worth of playlists to keep them interested as they drive... ah well.

I often have waves of finding new music like you, but less than weekly... I tend to obsess over a particular album or two until I become hyper-familiar with it and each little nuance before moving on... then returning back at a later date to repeat the joy =D
