Hello how may I help you? I need help with my playlists. Sure, which music app carries this playlist? Soundcloud. Sure, and what would you like to do with this playlist? Retitle the playlist called "rock". What's the original title of the playlist "80s" Okay I've gone ahead and replaced the tile "80s" playlist with "rock." Anything else I can do for you? Nope, that will be it. Okay, have a wonderful day!
