Good but needs more
Hoping it will support Apple Music and iCloud Music Library cause unless your music is actually downloaded onto your iOS device, it will not work.
Also, it would be nice if the app could include its own video player. I use it a lot to cast my vids stored on Dropbox or Google Drive but it is unfortunate Im unable to watch the same vids in my device when I dont want to use my TV.
Other than that, I find the app works quite well.
