Do you play songs that makes the audience happy, or you play songs that you personally enjoy?
Both of these and a third element. I also choose songs that make my band happy. Without them I'm just a dude with a bass. I've spent a long time assembling a crew of guys that I would trust my life with (musically speaking). If the band is not happy its members will eventually leave. I would have to say that it's an even three-way split between the happiness of audience, me, and band members. It's definitely not all about me...me...me.
