I got it to work, but I didn't use the playlist file that was suggested.
My DP channel has the "Hero" layout.
The top row is "Featured" and I have put the tag of "featured" on 7 or 8 of the songs on my channel
The next row is titled "Play them All" and it allows the full list of songs to play through. Then I have songs from the 50's, 60's and so on.
My categories are listed at the bottom of the JSON file and they look like this:
"categories":
[{"name":"Featured","query":"featured","order":"most_popular"},
{"name":"Play them all","query":"pre50 OR the50s OR the60s OR the70s OR pre2000 OR post2000","order":"most_popular"},]
It does take a few seconds for the next song to start because there isn't a way to "prebuffer" them using direct publisher, but it does play the full list of about 50 songs because is has all of the categories that I use.
Until I get the SDK figured out, I'm almost there with that, that's what I'm sticking with.
