I think this is very interesting about Billboard Top 100 artists, however there are TONS of artists and bands that have never cracked the Billboard Top 100 yet have been making music and doing live shows for years/decades successfully. I would guess/assume that these artists vastly outweigh the # of artists who have had a Top 100 song or album.

While I'm sure most artists would love to have a Top 100 album or song and the associated wealth it brings, I feel many would also love continuing to create music and tour on it while making a decent living for years. Leaving out these artists in the discussion I feel skews the point of the article.
