Admittedly this is probably more a personal thing -- i.e., the way *I* approach streaming services, versus anything inherent in streaming music per se -- but when I go to youtube et al and type in (just for example) Chick Corea's Now He Sings, Now He Sobs I am way more likely to then go and do something else while it's playing...cook dinner, surf the internet, balance my checkbook, etc. Whereas when I go to the shelves where the CDs are stored and pull out Now He Sings, Now He Sobs and put it in the CD player and press Play, I am far more likely to sit down in front of the speakers and listen. It's because the physical medium (CD or LP) is a token or talisman of the listening ritual.
