I have a Samsung S4 LTE running Kitkat, and an HP Probook running Windows 7. Have also got the latest mobile update for spotify running.
I had a few .wma files lurking on my Samsung of Acoustic versions Marianas Trench did on their Face the Music E.P., and on their deluxe album of Masterpiece Theatre. They are legal versions taht got sent to my Samsung when I upgarded my laptop, before I had Spotify Premium. Anyway, I have today converted them to .mp3 from .wma and they play fine on the laptop. 2 of the 3 in question producing this issue are also downloading to the device and playing fine on that too.
However Files #1 & #2 are not able to be put into "Saved Music" - the main place I shuffle from when driving. I barely use playlists.
The third file was not even needing to be converted to .mp3, it was already saved as that, but it wouldn't download to my device - kept showing as greyed out, unable to download and giving me a message saying unavailable.
Deleted all three files from Spotify on my Pro-book and went to re-attach them to Spotify. Now only Files #1 & #2 will go onto the Laptop version, and onto the device. File #3 won't even go onto the laptop.
All 3 files are greyed out on the laptop and unable to be saved on the laptop's Saved Music file either.
