I’m currently converting my CD collection to FLAC files and storing them to a NAS Drive that will be attached to my wifi router. I have a Yamaha A-S501 integrated amp and I’ll be adding a Google Chromecast Audio via the Optical input. I plan to use my iPad to allow guests to pick from the albums in the collection so I need to pick some music player/music manager app that allows me to do this via Wifi. I’d also like to limit the guests to selecting only Albums and not single tracks- trying to get back to how we listened to music when quality of the music was the most important aspect! Any suggestions on the player app would be appreciated!
