So, the audio.get method, which returns the user's playlist. At some point, he began pulling audio recordings that are available only for the web version.
I checked the WindowsPhone application, pulled out their client_id from there. In this situation, everything works as it should - a playlist is pulled out, but without links. Do they have their own personal API or what is it?
Ultimately, I need to get the WindowsPhone application to work: Return a full playlist without links. Any ideas?
