Add new Songza styles playlists

[jwdempsey]

Is it possible to get this data in the Mobile client?

[dylanPowers]

I was just wondering the same thing hah. After digging around a little, they aren't even appearing in the results for the search query. I'm thinking it will require an update to a newer api

[simon-weber]

I haven't looked into it at all. Here's hoping it's not too difficult to support!

gmusicapi/protocol/mobileclient.py indicates an API version of v1.5, while my just-launched Google Play Music app on my Nexus 5 reports using v1.9 now, at a different URL. It makes a POST to https://mclients.googleapis.com/sj/v1.9/listennow/situations?alt=json&hl=en_US and appears to use the same kind of Authorization header. The post body just now was {"requestSignals":{"timeZoneOffsetSecs":-18000}} which is how it determines time of day, I presume. It returns some JSON in the format:

In response to hitting play on the first returned section and first station, it made a series of requests, which appear to perhaps be already (or almost-already?) supported by ListStationTracks and GetStreamUrl...

which ultimately 302'd to a /videoplayback URL that had the mpeg data. So it appears to possibly all "just work" but it's hard to say for sure unless I fork and test it myself, maybe tomorrow morning...

That sounds promising. Playlist support would be a great addition!

[simon-weber]

nice work @LouisStAmour! looks like it should be pretty easy to support.

[ghost]

Hi,

is there any progress on supporting Playlists?

[simon-weber]

Sorry, I haven't done any work on it.

[thebigmunch]

These are the Listen Now Situations I implemented in #460 for another issue. Didn't make the connection with this until looking back at old issues and reading through this one. Should be able to close this.

[simon-weber]

Sweet; thanks.
