Stepping aside from the language problem for a moment, since I’m guessing it’s probably more important to get the basic entries for English language correct first.
Let’s take highstrung’s earlier presented example of the 'Maroons album.
It’s an interesting one, because while I think it is a rare case, it is a challenge to my proposal that should be addressed.
On the album for track 1 it says: drums.
Without listening to the track, my suggestion would be to enter that as ‘drums’.
Because, that’s what it says, doesn’t it?
I wouldn’t choose ‘drums (drumset)’, because I can’t be sure of that at that moment.
I wouldn’t choose ‘drums (unspecified)’, because we know from experience that in pretty much all cases where it says ‘drums’ on an album, it is a drumset, and not something unspecified.
I wouldn’t want the vast majority of drumsets on recordings being called ‘drums (unspecified)’ on MusicBrainz.
So, ‘drums’ it is.
But now I have listened to the track, and I found out that it is conga’s being played, not a drumset.
Then I should change the instrument from ‘drums’ to ‘percussion’, or to ‘conga’. (or to ‘membranophone’ if that makes somebody happy
So, for this example, using ‘drums’ in the first place could be considered slightly wrong (following my own line of thought), but it doesn’t do any harm, it is exactly what it says on the album, and can easily be corrected when more information is available.
So this leaves the question for me:
If ‘drums’ is not a valid first choice, what do others believe that should the default choice when a release says ‘drums’, and you have no additional information?
