hello, superlate to this discussion (I dunno why freso's ping earlier I didn't notice :o) but I like this idea:
following with onward discussion it should be "drum set" also?
and I am not opposed to bass (electric bass guitar) either
This is true, I myself was unaware of this/this distinction. and surly many others are also unaware of this.
I agree with these sentiments by zas and outsidecontext, however instrument credits have some unfortunate limitations, as https://tickets.metabrainz.org/browse/MBS-9327 illustrates.
In closing: please create some JIRA tickets with these changes (I can also bring them up on the meeting wrt style etc. for these things if it's wanted.)
