iTunes supports play count and always has, and I and friends have made use of it extensively (albeit for ourselves not shared) including for things like smart playlists where it's great for natural curation/discovery. Now that it's mentioned, I don't actually know if iTunes made use of the ID3v2 tag or its own database for that. Our music libraries are synced across devices and it seems to carry around fine, or at least close enough since a bit of fuzziness doesn't actually matter much in this case. A play count of 60 vs one of 61 or 62 isn't particularly meaningful since both show roughly that this is a song you have listened to quite a bit. It is useful though. In the iTunes implementation at least I think (I haven't checked in a decade or more, it was like this once but not sure about the latest) it only advances when a song is completed, not when it's started. So having a song come up one doesn't like that they immediately skip will appear in the number as the years go by.
