I have most of the music I ever liked on a USB drive that plays through my car stereo when I travel. The genres are all over the place, but what I listen to in any given moment depends on my mood. Sometimes I skip over the oldies, sometimes not.

So in my case it isn't a matter of not liking formerly favorite songs anymore, it's more of a selective yearning for a particular place and time that I want to re-live through the music of that period. It's all interesting, but not all at the same time.
