I have a large CD collection that I rip to AAC via iTunes. I then transfer to SD card for listening on my phone (currently Samsung Note 8). Prior to using Spotify, I used MS Groove and it would always play music stored on my phone. Any downloaded music would appear in my music folder along with my ripped CD's. In spotify however, it can 'see' my music library however it always streams the music rather than playing from the music stored on SD card. To make sure I can listen to my ripped music wheb offline (for example on a plane) I have toi make sure I've downloaded it via Spotify. Seems ludicrous to download from Spotify again when I already have it and Spotify can 'see' it in my music library as well! Is there any solution to this??
