Find a vampire, let him turn you, then you live forever and can listen to all the music you ever wanted to. Problem solved. And all you pay is your immortal soul. Seems like a good deal to me.
Seriously, what do you expect people to answer? Listen to what you want to, when you want to. Decide maybe this week to listen to, say, metal, next week (or month) to ska, next to prog. Maybe. Or make each day a specific genre day. Or here's another idea: turn off shuffle! Bloody hell, it's hardly a problem to have too much music to listen to, and not enough time. Just make some. I seriously don't know what you think people are going to reply with?
