I was trying to explain to a friend that someone is no longer available on Spotify earlier today so I said the sentence:
The Avalanches are no longer available on Spotify.
Immediately after saying that I realized it might be incorrect (English isn't my first language so this is a common occurrence) because if you take the name of the band out of the equation the sentence becomes of the form:
[Band name] are no longer available on Spotify.
which shouldn't be using are but instead be using is.
I asked around and some people responded saying it should always be is which confused me even further.
Is there any rule for referring to a proper noun as a plural or not in the case where the entity sounds plural?
