If you, like I have, been compiling a disk full of music for a decades and want something that plays on all your devices has easy download for offline and easy album art update, and web search right from the app and doesnt cost a bunch. MusicStreamer is perfect. Havent enjoyed a music app this much since Winamp! Also it will discover 20k files pretty quickly and did a great job of that. I highly recommend apps from this developer because the actually answer support requests!
MusicStreamer is available for download on the iOS AppStore.
