My Internal Jukebox

Ever get a song stuck in your head? I think it happens to us all sometimes. Earworms, I've heard this phenomenon called. 

I always seem to be humming or muttering songs under my breath, usually something I've heard on the radio, or tv. Working in accounts receivable, this can become hilariously inappropriate when that song is "Bitch Better Have My Money".

But I also have an "internal jukebox". This seems to be where my brain chooses independently of any outside stimulus (that I can discover) to start playing from its own stored reportoire. Songs I have not heard in years, or sometimes don't even know where I heard them. 

For example, last night when I went to bed I realised that I'd had a Bryan Adams song running through my thoughts all day. That song was "Have You Ever Really Loved A Woman" and I swear I have not heard or even thought about it for over a decade. RANDOM. 

So in addition to the incessantly catchy ad jingles and latest chart-topping hooks that I am bombarded with daily by media, I seem to have my own little radio station inside my head that sometimes chooses what tracks to spin in my thoughts. 

I'm curious to know - does your brain do this? I wonder how it chooses what to play next...
