I've created MP3s in MusicMatch. TT shows that there
is an ID3v1.1 tag for each file containing the Artist name
and Album. The v2.x shows it as blank.
I select the tracks (in v1.1 view), right click and
say "Copy 1.1 to 2.x" OR Sync. Both Artist and Album
are ticked to be changed. I then click on the Write tags
(and I've tried skipping doing that too).
Then I click on the file again, go to ID3v2.x, but nothings
changed.
You can email me at marsh@lucent.com if you want
more details, or an upload of the MP3 file.
