I don't know anyone other than myself buying music now.
Almost everyone has now switched over to streaming services—primarily Spotify here.
When people come over, they are surprised that someone who is obviously into music, only has such a “limited” library compared to what they can access on Spotify.
They don't understand the quality argument—the 320K premium stream is good enough and vinyl is seen as the “quality” option these days.
Computer-based setups are either confusing to many of them, or something they actively don't want.
People want to spend less time in front of a PC these days.
They bought into either Sonos or AirPlay and are used to controlling everything from their iPhones or iPads.
They have essentially discarded all of their old media. They don't care about loading up their devices with music, or serving music from a PC to their speakers, since they can just do it directly from their phones. Why add something to complicate matters?
When they visit, they still have access to all of Spotify’s library and all of my AirPlay devices just show up for them.
They don't have to configure anything or install a new app. I don't know what the situation would be like with Sonos devices, but I do know that DLNA is useless since guests can't send audio to it.
When I used to have shelves of CDs and a multi-CD player, we'd decide what we wanted to listen to together, but that's long-gone.
Most don't care about accessing my library now, and for those that do, I have to hand them one of my devices since JRemote is a paid app, it requires a password/access key, and even if it got that far, that now gives them external access/control to my media, which I don't want.
The app really needs to be free, and have a guest mode where the password is optional, it only gets local access with completely separate library views, and only has access to whitelisted zones.
Maybe make the current functionality an in-app purchase if you don't want to go totally free.
I don't know how I would sell them on Media Center to be honest.
It doesn't support the major streaming services, doesn't transmit or receive AirPlay audio, and even I can't get it to do synchronized multi-room audio so there's no chance of it replacing their Sonos system.
If it aggregated multiple services and treated them no differently from local music, that might be something of interest to people. But it has to work with their existing music systems first. There needs to at least be a free version of JRemote and yes, AirPlay support, for it to convert anyone. And I think Sonos already does that?
