Can't download cut files to mobile

[sbayer]

Hi,

due to a certain reason (see below ifyou're interested) I've cut dowm some local mp3 files to 45 seconds. After having done so, I integrated them in a spotify playlist (Cortinas) on the PC. As they are now in the PC playlist, I can integrate them in other spotify playlists. BUT: these particular files won't play or download to a mobile device (Samsung Galaxy S5). Any ideas?

Your input is higly appreciated!!! 🙂

Reason: I want to use spotify as a source for music on a tango argentino dacing event. Every fifth file is just approx 45 sec to give chance to separate and find a new partner to dance. That's a tango argentino cultural thing ...
