My music dilemma

So I decided to ask my 17 year old sister, who would be good to listen to, while working out. And she gave me this huge pile of cd's to download onto iTunes. I am 8 years older than her & usually end up feeling like an old fart, compared to her. But not yesterday! I had actually heard of some of bands she had mentioned & even actually owned a couple of the cd's that she was going to let me borrow. Isn't it nice when you suddenly feel "cool"?
