I've been developing a music Service for Sonos and have everything up and running. The problem I have is Sonos only requests 99 items through it's getMetadata call, some of my libraries have 300+ tracks in, so I'd ideally like to list them all out.
I can't find anything in the Sonos api documentation about how to list 100 or more items but I'm assuming it is possible because their reference page for getScrollIndices (http://musicpartners.sonos.com/node/103) alludes to a library much larger than 100 tracks.
