Xor not working with more than 1 song

[Lory955]

In fw 5.1 I can only set up 1 song in .json file.
More than 1 cause xor:play won't work.
Maybe I'm doing wrong but I don't think so.
I can still play music but just one.
If I assign audio.mp3 to home menù I'll not be able to add another song.mp3 to another application and viceversa.
