I downloaded Spotify this morning and, as far as I can tell so far, OOP or hard-to-find music doesn't seem to be their thing. There are a lot of compilation albums, which I normally never touch, but there's such a volume of stuff that I'm finding lots to listen to so far. Today I've heard Horace Silver, In Pursuit of the 27th Man, Clarke/Boland Big Band, More Smiles and Stan Getz, Complete Jazz Series 1946-1949, all new to me. Mind you, at the moment I think it's only available to us Yurpeans.
