I'm an old fan of classic rock, progrock and so on music. I have more than 250 playlists - very well composed playlists of such music. Last few months I discovered that Spotify trying to reduce its library: removing duplicate songs from their servers, deleting usual albums but leaving expanded etc. I think much users know it already.
But today I see very strange and very dangerous thing.
Many of my playlists lost tracks over 10 minutes long. You can check the next albums for example: Wishbone Ash by Wishbone Ash, Pilgrimage by Wishbone Ash, Get Ready by Rare Earth (original Get Ready song 21'32'' long - lost), Cosmo's Factory by Creedence Clearwater Revival, Blind Faith by Blind Faith and many more. All of them lost long compositions (longer than 10 minutes).
I don't know what to do now. I see no subtitution for the lost.
And of course I already start to duplicate my library on other streaming service.
P.S.: I have premium Spotify subscription for GB.
