Hi whenever I try to shuffle my personal music library on Google Play Music the app displays the ‘busy’ spinning circle on the screen for approximately 10 or 15 seconds and then it times out with the error code 1002 (and occasionally 1001). I believe this is because I have over 10,000 songs in my collection on Google Play music. If you’re unfamiliar with GPM it allows you to upload your entire personal music collection to the cloud for free and play them any time you want from any device, so over the years I have amassed quite a big music library via this service. I suspect the problem is one of either two things or both. There may be a limit to the number of songs that can be added to the Sonos app playlist at any one time or/and the Sonos App will wait for a response for Google Music (and maybe other similar services) for only a given period of time and if it doesn’t receive a timely response, it will error out either with error 1002, or error 1001 and will assume there has been a network error and a failure to communicate with the GPM servers. This of course is an erroneous assumption, as naturally it might take up to a minute or more to build a playlist containing 10,000 or more songs. The solution would appears to be to allow a longer period of time for larger playlists to be built. In the past I have had over 19000 songs in my collection, so again setting too short a time out to build large playlists does not appear to be a wise choice in this instance.
The evidence that this is the case can be demonstrated by the fact that I can play singe songs or shorter playlists from my collection, such as sons by a single artist, albums and a particular genre. The app always times out at exactly the same time - which although I haven’t measure it exactly is about 30 seconds or so.
