Hello, 

i've imported a couple of songs from Itunes, they are perfectly readable on my Mac (the one which the songs are saved on). Those same songs appear in grey on other devices (iphone, ipad...) or sometimes don't not appear at all. If it appears I can't download it on my iphone (it says to go on my 1st device, open the same playlist and play the song and it should magically appears on my iphone playlist but it doesn't....).

If i play the song on the 1st device and change the player, it plays another version of the song (the one available on spotify and not mine from my computer) or it doesn't play at all...

How can i play files saved on a computer, not available on spotify by the "normal way", on all my other devices (iphone ipad)?

ps - I've noticed the the files not readable on other devices haven't any sign before their names on the playlists (nor "+" nor "v") -> btw what doesn't those signs mean? 

thanks in advance 

🙂
