My home music server has my wife and I’s mp3 collection that we’ve been building since like 2000. However, I’m continuously buying new music on bandcamp and scouring music blogs, and the collection grew until she was overwhelmed by the selection. So then I took her old click-wheel ipod music collection (which broke, but she had the music backed up), and I put that on a USB which is plugged into our Yamaha Musiccast receiver. The interface is pretty simple in the musiccast app (scroll and choose). She’s happy to have her collection locked to like 2012 in an ipod-like fashion.
But she still misses that ipod. The screen started fading, and I took it apart to replace parts, and in the process I screwed up the battery. It only works when docked and dies immediately when undocked.
I'd just be using WG if I figured out how to set it up the first time ahaha. It's nice to get rid of third-parties whenever possible, especially when it comes to my personal IT infrastructure.
