I created a few files in Audacity, then set Spotify to recognize them and saw them listed on my desktop application. I can play them on my computer but I cannot play them on my devices. I have a Samsung S5 giving me "This track is not available" when I attempt to play it and an iPod touch giving me "track not synced." If it is listed as a file in the iPod, then it is partially synced, and the S4 confirms that something buggy is happening.
I tried in an iPad and it gives "track not synced" and when the attempt to sync is made, it doesn't get past the initial green bar. It will not fully sync. Please help.
