A:Answer From the main smart TV menu, if you scroll left to the apps menu both Apple Music and Apple TV are available apps preinstalled. Spotify also comes preinstalled, and you can download tidal, pandora, napster, iheartradio, etc if you are looking for other music content. It also supports connecting to a phone, I will be playing a song on Youtube or Spotify on my iphone and then send it to the TV and use my phone to select tracks to play while doing chores around the house, so you don't have to fumble with the remote to navigate playlists or search.
One word of warning though, the speakers are adequate, good even for a budget TV, but they aren't great. If you need good sound you will probably have to add a decent amp and speakers, but if you just want to have some tunes on while washing the dishes or whatnot then it is fine as is.
