Apple

seemed about right for me with all the data. it tracked all iphone and apple music app on windows plays

Same. My top played song shows 12 plays. I listened to that song probably 12 times in a single day and I still don’t think it’s my most played song. It’s a joke.

Mine is 23 and for a song I know I didn't play more than a few times (it's an obscure classical track) but I know I played a lot in 2021/2022. It seems to be skewed by older data for me.

same. granted my plays were split between Apple Music and Spotify. But I know I listened to my top song more than 20 times in both apps.

My top played has 152 so it seems correct

Also doesn’t count anything I play on Sonos (using their integration). I know because I always play some ambient/chill music and that would be at the top of everything.

Hmmm mine was pretty accurate. Well into the hundreds of plays with artist play on the thousands. Are you sure you’re only using Apple Music?

If you have owned music and don't just stream subscription stuff, I believe it will not count iTunes Match music. Of course it might only be matched songs that aren't in their catalogue which would make sense.
