From the Plural to Singular aliases thread:
NWF_Renim said: I think it should be drums -> drum and then for the instrument set (such as in K-ON!, etc) it should be drum_set with the implication to drum.
I thought it deserved further discussion. I like NWF's approach, if we can get people to use it. I've also heard "drum kit" used too, though it may be a dialect thing. Thoughts?
