I sing along or change lyrics to most anything, but rarely listen to the radio. Music is one of the only aspects I do control so I try to focus on what I want to listen to in order to control my emotions/mind.
I can't say for sure. I remember having a radio in cars in like, high school. But I can't recall ever asking for it to stay put. Though now with custom music and playlists I tend to play a few of my favorite songs over and over. Most of my good memories from my youth were as a little preteen. So late 90's. One of the best songs I can remember, and even today I'll play it three or four times is One Headlight by The Wallflowers. Just one of the best songs as far as lyrics, tempo and meaning.
