While many stations rotate their music selection, are there some stations that you've found have become "stagnant" and keep playing the same songs day after day, year after year, with minimal change? My local "Jack" station is a little like that; in the past, they have rotated more, but lately stays the same. WZYP is another station I can think like that, as their recurrents/golds have stayed the same for years. What say you?
