Women were fainting at the feet of the Beatles for years. They released 12 studio albums (too many) which definitely classifies them as a "greatest hits band."
Nirvana
Nirvana was an incredible band who did a lot of things that other bands never thought of doing. They were popular in their time and even more so after Kurt Cobain committed suicide. After that, they fell into the overrated category as companies profited off of their grim past.
