Note: Spotify is probably required to do this as a condition of their licensing agreements with ASPCA, etc. Different terms apply to streamed music vs downloaded music, so offline-caching of music would have required negotiated exemptions from the licensing organizations. They probably had to limit the period of time that a downloaded song could be accessed offline. If you listen to these songs so much, just buy them. If you're a programmer it should be pocket change for you.
