I firmly believe that there is an incredibly catchy Irish-style drinking song, the type you can't help whistling along to even if you don't know the words, that is known in all Beleriand.
The problem is that it has two sets of lyrics, with wide debate about which is original. One set mocks the Sindar for hiding in the forest rather than fighting and generally being less scholarly. The other mocks the Noldor for killing elves as often as orcs and being bad at wilderness exploration.
After a several violent bar brawls, Gil-Galad bans the tune, both sets of lyrics, and any poems with a similar meter from being performed in Lindon.
This works for about six hundred years, until they find out there's a third set of lyrics and Elros made it the national anthem of Numenor.
