On Twitter, a user with the handle noisejourno asked about band names, writing
Collective nouns, such as the word band, are generally singular in the United States; but for band names, most people go by the rule that if the band name sounds plural (like the Beatles or Black Eyed Peas), they treat the name as plural, and if the band name sounds singular (like Fall Out Boy or Coldplay), they treat the name as singular.
So in the US, you’d see sentences such as “The Black Eyed Peas were amazing at the Rose Bowl” (treating Black Eyed Peas as plural because it sounds plural), and “Coldplay is hitting the road this summer,” (treating Coldplay as singular because it sounds singular).
But now I need to point out a British English versus American English difference:
British writers are more likely than American writers to treat all band names as plural. For example, it’s easy to find British publications writing about the recent Coldplay tour with lines such as “Coldplay are the headliners,” and “Coldplay are asking their fans to submit requests for European tour dates.”
That’s your Quick and Dirty Tip: If you’re in the US, treat band names like they sound—singular if they sound singular and plural if they sound plural—but if you’re writing with British English, treat all band names as plural.
