Even though I prefer many Bob Marley songs over this, "I Can't Help Falling In Love With You" is definitely better known than any Marley song (or any Reggae song for that matter).
No Woman No Cry
Buffalo Soldier
One Love
...all bigger than Elvo his hits.
His legacy isn't limited to the stoners who wear his ganja tshirts and don't shower
If Beyonce had never had Blo she's still be sittin pretty in the 3rd tier with with Pink.
What a joke. I don't know why I argue with some of you. The fact that y'all even think Rihanna will have a legacy over Beyonce is just too much for me right now.
I really think Bey should stop with this album. Literally everyone believes she's way bigger than what she actually is so she could leave on a good note.
I do think she is a legend tho, the only people who'd deny that are the Navy
You can make an argument for One Love, but other than?
Three Little Birds
Get Up, Stand Up
Redemption Song
I Shot the Sherriff
Is This Love
All v recognizable, I think? Just look @ his YT views?
I could name you the titles of some Elvis songs but not a clue here on what they sound like.
And EP was actually successful during his time, while Bob's catalog didn't gain any traction in America until after his death.
Y'all don't listen to anything but today's pop and scattered amount of pop music of the '80s and '90s by Madonna. Of course, you wouldn't know or care to look up an Elvis or Bob Marley song. Still, both are massive icons.
I think 100k+ is possible in the US as well.
