My Question or Issue

I have many songs downloaded on my phone for offline listening, but when Spotify opens it requires an internet connection to load My Music and everything else. That means if I open Spotify when I'm already out of service (e.g. on a plane), it doesn't know which songs are already saved for offline listening and I can't play anything!

Please update the app to have a cached list of all music / downloaded songs so users can play them even if they forgot to "preload" the list while they had internet . . .

I posted this issue before and it was erroneously closed by a moderator. This is not an issue, but a suggestion for improving the iPhone app
