Hi Splitkpb,
Thank you for posting in Apple Support Communities. We'll be happy to see how we can help with Apple Music Replay.
It should be using your listening history to gather the songs. Since your not seeing anything updated, follow the steps below we found in How to get your Apple Music Replay - Apple Support.
If you don't see Replay
You might need to play more music. Look for a progress bar on the Replay site to see how much music you need to listen to. As soon as you've played enough music, you'll get a notification that your Replay is ready.
If you still don't see Replay, make sure that Use Listening History is turned on for all of your devices:
* On your iPhone or iPad: Go to Settings > Music and turn on Use Listening History.
* On your Mac: In the Apple Music app, choose Music > Settings, click the General tab, then select Use Listening History.
* On your Android: At the top of the Apple Music app, tap the More button
, tap Settings, then turn on Use Listening History.
And you can use the link above to learn more about Apple Music Replay.
Reach back out if you have any questions.
Take care!
