Query: Lithium was NOT written by this group

It is true that this group was the orginal Nirvana, but when the 90's Nirvana came out they were more famous then this group would/could ever be and they got into a legal situation with the name and it was seattled, just because the song "Lithium" by the 90's group Nirvana is on this Box Set does not mean that the 60's Nirvana wrote it. The 60's Nirvana covered Lithium. IT IS A KURT COBAIN SONG NOT A SONG BY THIS 60'S NIRVANA!
