With Google's "Scan and Match" feature, I understand that when I go to upload new music, Google will scan the music prior to uploading, and if Google has a copy already, it just adds their copy to my music collection online (instead of uploading it again). Sometimes Google's copy is higher quality than mine, so I would like to apply this to ALL of my music (including already-uploaded music). Is there any way to do this?
The alternative I see is to just delete everything and start over, but that sucks. 🙁

It looks like this will be happening automatically over time. Here's the relevant portion of the Google Help page on the feature.
