Yeah, yeah, yeah

I've reached Thing 20 'Mobile music' which looks at music, streaming music sites, and the distribution of music to mobile devices generally.
I checked out a heap of online music delivery sites earlier, see Free MP3s post
I used to access LastFM till they asked for [payment (knowing the music wants to be free) it now requires you to download Spotify. I feel that the free version of Pandora is better and easier to navigate.
Looked at Freegal, which has been subscribed to by some of the city libraries.
Re streaming music - true, the way music is distributed has been revolutionised. More and more people subscribe to streaming services where you pay for access to a big catalogue of music instead of buying an album or downloading a single.

Totally different to actually going to a physical music store and flicking through CDs, cassettes or even vinyl records. Though with the renewed interest in vinyl LPs could there be a resurgence of the Brashs or Allans music shops?
Going even further back in time is the record selectors in cafes, milk-bars etc. where for a few coins you got to select your song from a Wurlitzer style machine - so American soda - a time when Top 40 charts meant record sales, not the number of downloads.
So music in libraries - demand still seems to show a preference for borrowing CDs, and often CDs of times gone by. 
Playing on demand and 'ownership' of the music may still be a factor rather than the here at the moment gone in a instant streaming services. Time will tell.
