Worst Rock Band Ever !!!!

In defense of Blue Cheer--I like Summertime Blues and the flip side, Out of Focus.  Kind of proto-punk, proto-grunge.

I will really go out on a limb here and say U2, Kiss, Phil Collins

That indeed is a LONG LIST.  For me, its almost entirely about how good the vocals are LIVE. The right gear and effects musically are not that difficult to make a good guitar/keyboard/bass player sound exceptional.

Where you separate the good from great are the vocals.  Ive seen TONS of live performances over the last 35+ years.  So many of them were so-so to aweful when it comes to the vocals.  In fact its EASIER to point out which band were incredible live becasue the vocals were spot on.

i also don't get the praise for foo fighters, whose music has devolved to generic, soulless arena rock. i gotta say, however, that the eponymous first album, which grohl played by himself, is a tight, ragged little masterpiece--he had a bunch of good tunes stockpiled before his muse fled. i've always like  "learn to fly" too.
