I run MP3Gain
on all my tracks. It adds a type of ReplayGain APE tag to indicate what it did so that it can be undone.
I happened to be checking a few tracks in MP3 Diags
because of another issue and noticed that the tracks that I'd run through MuvUnder Cover had a variety of errors that indicated that the APE tags had gotten messed up. The tracks that hadn't been edited in MuvUnder Cover still had good APE tags.
I did some quick tests and confirmed that MuvUnder Cover was causing MP3 Diags to report the issue.
MP3 Diags seems to show that the APE tags have gotten partially written over with some other data.
Now, this could definitely just be a MP3 Diags reporting glitch, but I thought I'd run it past you first since MuvUnder Cover is causing the change that MP3 Diags thinks is an issue.
Any thoughts on this? I'd be glad to send along a "before" and "after" track if you'd like.
