Personally, I go through spells of listening to music and not listening to music. Currently, I have the Pandora App on my iPhone and tune into the customized station of my choice whenever I go out for a run or workout. Right now it’s ‘Beats Antique’ radio.
As far as music for my clients, I agree with the other postings…. listen to whatever the clients enjoys most. I still suggest using Pandora, just pop your iPhone into those little portable speakers and set it on a station that they enjoy.
