Here is a list of popular bands with the name spelled wrong
1. KoRn
2. Led Zeppelin
3. The Beatles

5. Lynyrd Skynyrd
6. Weezer
7. The Jimi Hendrix Experience
8. Metallica
9. Megadeth

That's 10! Metallica counts because they made up that word. Wait! I almost forgot
11. P!nk
This may seem like a rant, and hell, it very well could be. Just giving fair warning here.
Jimi Hendrix Experience: They changed the spelling of his name and it's not a drastic one so I don't see the problem here.
Metallica: If the word is made up, how can it be misspelled? Yeah, that's what I thought.
OK so as a musician I take offense to the initial post here that it implies musicians can't spell. Maybe I'm taking it the wrong way but I take my craft very seriously. Look, some times a band is forced to change the spelling of their band for legal reasons if they want to keep the same "name". Now I'm not saying that I'm a fan of how some of these bands spell their names, but you gotta look at it from their perspective. Other times it's just a way to get more attention, which is fine in it's own right. My band, we didn't change the spelling because as far as we know we're the only band out there with it. We're currently going through the process of having it Trademarked to avoid bullshit later. We didn't feel the need to change the spelling at all since we just let the music speak for itself as well as our live performances. I can't speak for the entire musician community but that's just my opinion.
Bottom line, if you don't like a band/group simply based on the way they spell their name, then you're pretty ignorant for not giving it a fair chance.
