Hi Florian,
I don't know of this is a error (mp3tag v.2.16k), when I write this in my html template (tracklist) %_length% gives this results: 3_35 in stead of 3:35 (version 216i ok)
Now i replace it with: RECORDLINE06=<td>$replace("%_length%", "_",":")</td>
this results in 3:35 and works fine as like the older mp3tag versionnumbers.
Grtz. Billy
