Does and Doesn't

I don't even remember why I have that song.
I can tell right away, it does and doesn't belong.
It was on the station I liked, a big hit all fall.
How many times did I hear it, and not like it at all?

When I hear it now, I hear the words and tune last.
First, I hear memories, which I still like the best.
I didn't like it then.  Now I do and I don't.
I could stop listening, could delete it, but I won't.
