A free playlist for the party. Send one link and everyone adds their songs before the night. You start with 3 hours, and more hours are free.
One tap: sign in to Apple Music and the whole night lands in your library, in order. Needs an Apple Music subscription.
One tap: sign in to Spotify and the whole night lands in your account, in order. For now this works for Spotify accounts on AUX's list.
Every song has an Apple Music link (A) and a Spotify link (S). Or copy the list and paste it into a free playlist importer such as TuneMyMusic or Soundiiz.
Ask the host to send it again, or start your own.
