Too much and too little are both two evils, but at least with too much you can always skip. Especially in our playlist days, you can easily create your dream album. I think I'd order the songs in a ballads pile and a blues pile. The blues pile will be perfect for early morning in the forest runs, and the ballad pile perfect for being knackered on the floor after that early morning run. Who said piles can't be a good thing? (That sounds wrong.)
