I don't leave talk shows or news-type radio on in the shop as it is far too distractive.
I particularly like classic rock, some old punk, some (not all) country, blues, some of the new rock (rock, not bubble-gum stuff).
Of course Lemmy, Jimi, Stevie, Angus and Eric all have their music in my shop. Classical music is sometimes played in my car, never in my shop - it just never works in to things. Yes, bagpipe music does play in my shop too.
It is nice to have some variation in the music during the day. However, I keep the 'trend' fairly close; no new stuff on the same day as classic rock, etc.. It can be distracting. Rather than trying to watch a clock all the time, I make up CDs for my player and try to have them last sixty minutes or so. That way, I stop on the hour to change CDs and I can keep track of my time.
