Hello fellow HN swiftie. I've also been pondering creating some (non copyright infringing) Taylor Swift app recently. Something like this is always a good idea as I'm constantly doing double takes to make sure I'm listening to Taylor's Version whenever a Red or Fearless track starts playing. I wonder if this would be possible too for Youtube playlists/suggestions, as that's my primary streaming music source. Also, since this app is written in Swift (natch), don't suppose there's any possibility of an Android port?
I know this is an unpopular take among reddit swifties, but I really miss The Swift Life app. When it shut down part of me wanted to reverse engineer the server-side to keep it going. It was a unique social media app and had a great, creative and artistic community. I even got free rep tickets from a friend on it! Also Taymojis. I still keep the app's icon on my phones homescreen, and launch it every now and then...
