Being able to have a 'Favourites' list and the ability to make custom playlists would be great!

There's been many times when I'm listening to a pre-made playlist and like one of the songs, but there's no way for me to save, like or favourite it so I can listen to it again later.

Custom playlists would allow us to tailor our own streaming experience without the worry of copyright or muted VODs. Instead of finding the tracks on Spotify and making a playlist there, it would be great to do this in the Soundtrack app where we can retain the functionality of having the current song being displayed below the stream player.
