Why does Walkout Song DJ let me add a song and then say it's not available?

[UpAllnite Software]

Walkout Song DJ will let you add a song if it has a valid file path in your iTunes library.

Sometimes a song can have a valid file path on the device, but apparently cannot be read by the iOS libraries used by the program. 

We did not encounter any of those songs in the testing of the application, but this scenario has been reported by a few users.

In versions prior to 2.1.5, these unplayable songs presented an error message box saying that the file can't be found on the device. 

That message was misleading and was fixed in version 2.1.5 to present a new error message explaining the actual problem of an audio file with audio tracks that cannot be read.

If you do encounter such a file and would like us to diagnose the actual problem so you could possibly use the song, then please post a link to the file or send a PM to the "UpAllnite Software" and we will take a look.
