on the topic, I think it's quite cool how someone will send you a song, and for the rest of your life, it makes you think of them.
likewise, a song may be playing during a fun time with friends or family and when it comes on shuffle randomly, you think of them and that moment.

so on a random thursday, when you're 43 years old and living in a different state, and you get out your wallet to give your son money for a corndog at the Major League Baseball game,

and for some reason, you hear yourself humming an old song,

I hope it makes you think of me.
