I did notice a couple of mistakes in lyrics, but that’s par for the course when it comes to lyrics available online. It might make a good discussion starter on “mondegreens” too. Mondegreens are misheard lyrics. The most famous is from Jimi Hendrix:
“Excuse me while I kiss the sky.” (actual lyric)
“Excuse me while I kiss this guy.” (mondegreen)
Pharrell Williams’ “Happy” seemed okay, but I noticed a mondegreen in Snow Patrol’s “Called Out in the Dark”
“This magic, this drunken semaphore.” (actual)
“This my chick, this drunken centerfold.” (mondegreen)
So, as with just about everything on the internet, read critically and don’t assume that it’s all accurate.
