I have been asked to control a music media server which basically supports TuneIn and music content libraries.
Is there any that you are suggesting and highly working with using an AMX reliable module ?
ReQuest continues to sell the same product line for the last 5 years that does these things well. We've integrated hundreds of them through the years going all the way back to 2003 or so. They leverage MYSQUEEZEBOX.com to provide access to the apps/services. They have AMX integration that we bypassed and built our own to provide full on-panel interactive content management and browse/search. Note that ReQuest is basically coasting now and will not typically add anything new nor revise anything if a service changes and the interface needs help.
We did the same full integration with NUVO but the same issues there: no updates of significance. But they do have a working AMX integration too.http://request.com/documents/Datasheet - F3.pdf
I only use spotify, and even then I don't really like it
