My music is classic hits now, too.I don't know how old you are (you look youngish) but I'm 37, don't really think I'm "that old" but I was listening to a song I grew up listening to and my friend said "wow that's a classic." I was like wow so now my music is considered classic/old...guess I am getting old.
The funny thing about age is that when you're really young, as in a teenager, you think people in their 20s were old, then 30's and so forth. When I hit my 20s I thought that people in their 40s were old, now that I'm at that age, I don't see people as old anymore! I mean, there's certain ages that people are considered seniors by society's standards, but age has just become a number. I look at my parents who are in their early 70s, and they are so young at heart and very active, that when I really sit and think about their age, I think that 70's doesn't seem "old"!
