a feature to replace song(s) with different files

[andrewrk]

Here's a user story:

I have Division Bell by Pink Floyd in my library. They're MP3s, ripped from way back when, kinda low quality. I'm also missing track 6, because I deleted it a while ago. But now I regret my decision.

Now I go on Qobuz and buy the album, in FLAC form. So I have a duplicate copy of this album but obviously I want to replace the old mp3's with the new FLACs. However, the play count and other metadata should be preserved.
