Some electronic music performers, particularly Deadmau5, have insisted that they be called "producers" rather than DJs, due to negative perceptions of the term held by those who do not associate themselves with the mainstream "EDM" movement for various reasons.
For unknown reasons, non-band-members contributing musically to Havalina Rail Co. albums would always be referred to in the liner notes as "Latino All-Stars" rather than guest musicians.
LL Cool J would like to remind everyone not to call it a "comeback", he's been there for years.note "Rocking [his] peers, and putting suckers in fear!"
Michael Jackson often referred to his "music videos" as "films" (even the standard 3-5 minute ones).
Related: in an interview, CÚline Dion stated that she felt that her video for It's All Coming Back To Me Now wasn't a music video. It was more like a "four minute movie".
Philip Glass is not a "minimalist". It is process music, thank you very much.
Certain bands (such as The Tragically Hip) have "The" as being the first part of their official band name — while other bands (such as the Foo Fighters) don't, but are still usually referred to with "the" at the beginning. In the case of the former, their ardent fans will correct you — if you leave off the word "The". Other bands (such as [The] Rolling Stones) are inconsistent with it, however.
Many fans of "real" bands (i.e. ones that play their own instruments) will insist on referring to vocal ensembles as "groups". For example, see any Twitter trending topic related to bands - it's a pretty even mix between those mentioning One Direction and those insisting "One Direction are a group, not a band!".
Whenever a popular rock band goes on hiatus, you can bet them and their fans will be using the word routinely when a non-fan calls it "a breakup."
