Nirvana "Smells Like Teen Spirit" (1991)
Tony Toni Toné "Let's Get Down" (1996)
Where They Sound The Same: The chorus. Listen at the 1:38 mark of "Let's Get Down" and at :50 of "Teen Spirit."
On the YouTube video for "Let's Get Down," one astute listener pointed out, "Guess Kurt's inspiration for music was Tony Toni Tone... hahahaha!!" Good point, except that "Smells Like Teen Spirit" came out in 1991, and Kurt Cobain was dead before "Let's Get Down" dropped in '96. To be fair, Kurt Cobain once said that when he wrote "Smells Like Teen Spirit," he was really trying to make a Pixies song, so maybe this is all just part of a big, strange cycle of influence.
