Comment 1 for bug 193722

By looking at the scripts, I can confirm this. But this bug can't be fixed completely because lame is in multiverse, so it can only be suggested.
I would also not depend on these tools in universe, because they are only useful if you have installed software from multiverse. Therefore I would say:

Recommends: id3v2, vorbis-tools, flac
Suggests: faac, faad, lame
