What does 乐助 (yuè zhù) mean? I think we've got some music biz jargon here:
【我们恋爱吧 第二季】EP12 @ ～20:09



The sentence:

我们的那个乐助说了

The person speaking often speaks of his band, so it is likely that 乐 is short for: 乐队. Of course, less specifically it could just be short for 音乐.
助 is a little more ambiguous. It could be 助唱, 助理 or something else.
It doesn't seem like a very common word. There aren't a lot of query hits for it online.
Ideas?
It is an abbreviation of the &quot;musical assistant&quot;, 音乐, or 音效助理 at a music production studio.
