This is probably not a show stopper so that's why I'm posting outside the release thread.

I used 9.0.143 to rip+encode hundreds of tracks, then categorized them using the MMJB tags.  But for some reason many of them have duplicate MMJB tags as below:

MPEG-1 Layer 3
320 Kbit CBR
44.1 Khz Stereo

This scares me since to me even though MC reads the MMJB tag info at some point they will need to get cleaned up and so I don't want to lose anything.

OK I think I found what is causing this.  On a track (below) that did not have any MMJB dups I corrected the Album Name then did a Rename File From Properties which caused dups to be written:

This problem is more serious than I thought so I posted it on the 143 bug thread ... meta tag data is ballooning!

This just started happening with a recent change to make the comments understandable by WMP9.

It will be fixed soon.

[Markeau]

144 seems to have fixed the dup MMJB id3v2 tag problems.  Plus, I wrote dummy data to, then removed it from, an unused field (Notes) which cleaned up the dups.

Good deal
