I remember when I first heard that Blink-182 song "What's My Age Again". I was like... 14 or 15 or something and that lyric, "nobody likes you when you're 23" just seemed so far away to me. "Wow. 23! That must be what it's like to be a grownup."

Now I'm 28 and it just makes me feel old.

What are some songs that have had the meaning change for you as you've gotten older? Or, alternatively, that make you feel old?
