I read Oliver Sachs Musicophilia:

In it he points out how some people with Alzheimers or other degenerative brain damage can use familiar music to co-ordinate a sort of 'flow' a rhythm of activity.

When I am coding it is like this. I can put on a familiar record that know back to front and then suddenly it is over and I haven't heard any of it but it has marshalled my flow for me.

Put on an unfamiliar playlist or a 'radio' style thing from (or the radio even) where I don't know what is going to be played next) and it trashes my flow.

So to get stuff out of Spotify I have to make and learn playlists (as it trashes the order of all the LP's which I have burnt into my head from years of listening to them on vinyl....)
