The only ones I can recall in the LOTR movies are the wordless chorus in Lothlorien after Gandalf passed and when Pippin sings for Denethor while he abuses a tomato.
In addition to what’s been mentioned below, in Fellowship Bilbo sings the first verse of The Road Goes Ever On and On as he departs the Shire for Rivendell, and in the extended edition Sam and Frodo encounter a party of elves on their way to the Grey Havens who are singing A Elbereth Gilthoniel as they travel.
Merry and Pippin also sing a drinking song while on the shire. Gollum also “sings” in the forbidden pool while catching a fish. In addition to what the others said.
There’s a fair bit of singing in the movies, granted I haven’t read the books in years to really compare.

There’s more of it in the books, be peeps definitely be singing in the movies.
Tom Bombadil sang a lot, but he’s not in the movie which really drops the amount of singing.

Aragorn definitely sings something. I can’t remember what or when, but I can hear the song.
He sings about Beren and Luthien in the first film and later at his coronation in the third one.

Merry and Pippin also redo The Green Dragon again at Theoden’s hall after Helm’s Deep IIRC.
