In sports, I always chose music to set the mood going into a game. If it was a big game and I needed to calm my nerves I would play country. If it was a rivalry and I knew I needed to hit someone, I would play something to give me an attitude.
For sales, oddly enough (I'm a chunky white dude) I listen to NWA. They have a strong sound and obviously, they have some attitude - things I think are positives on the phone.
What are your preferences?
