How do you choose your daily dose of music?


Sometimes I get music stuck in my head and just have to listen to it.  Other times during my daily meanderings I hear something (not necessarily music) that make me think of an album or song I want to hear.  Just a curious question.
Do you thumb through your library and choose or does one thing lead to another (this is typically my case)?
I certainly can find myself lost as in down the rabbit hole and it may last for hours. Do you find yourself going after music that is recommended here or other places, or by other people etc.

Most of the time I’m streaming from my music server using Squeeze system (Squeezebox Touch) and just select to play random tracks. When I think of something I want to hear I add it. When the last track in the queue plays, a plugin adds more similar stuff from Spotify, which still sounds pretty good, but not as good as my stuff ripped to full CD resolution. It’s a great way to discover the music that not just you choose own that might not get played otherwise but other similar stuff that you might like as well. I digitize my records when played and those get added to the library.
2 480gb iPods - all loaded up full at 128K- for car, or small shelf system as background music in house. A small nightstand for night time sleep music. Can not fall asleep well if music is not playing. 
 1 metal/hard rock. 
 1 rock/blues/everything else. 
  Don’t have a proper routine, just grab one and hit shuffle. 
  
Interestingly, doctor's use this same method when prescribing your daily dose of medicine.

fleabay. Some  use the SD cards which are faster and battery lasts a lot longer as no moving parts.
