There is a huge amount of music that is not available through the regular streaming services - much of it material by classic artists. Frank Sinatra: approximately 60 tracks from his period on Reprise (1960-1986) is not available to stream - including many single sides. Bobby Darin: The Shadow of Your Smile, In a Broadway Bag, If I Were a Carpenter, Inside Out, Dr Dolittle, Born Walden Robert Cassotto, Commitment albums are not available on Spotify. Only a "best of" are available on Amazon music. This means that hits such as Mame and If I Were a Carpenter are not available on the biggest of all streaming services. Neil Sedaka: Virtually all albums he made for major labels after leaving RCA are not available on Spotify. This includes Sedaka's Back and The Hungry Years. About a dozen albums - for major labels alone. Chet Baker: None of the five superb (not to mention key) Prestige albums from the mid-1960s are available to stream on Spotify or Amazon. Neither are any of "The Legacy" series, which contains much of his best work from the 1980s. And that's just the tip of the iceberg with regards to Baker because he most often recorded for small labels. Sammy Davis Jr: Only three of his album for Decca during the 1950s are available. He released about fifteen. Ray Charles: Only a handful of his albums for ABC in the 1960s are available to stream. The same is true of the albums from the next four decades for various labels And if you head into the area of classical music, the amount not available is staggering.
