Your meme, should you choose to accept it, is to rank the following bands in order, from COULDN'T LIVE WITHOUT to COULDN'T CARE LESS. To add value to this process, you must also add one band to the list, and remove one band from the list, before passing the meme on (including these instructions).'
From the good to the bad:
The Grateful Dead (my addition)
The Sex Pistols
The Red Hot Chilli Peppers
I dropped Radiohead because I can't remember anything about their music, therefore they are sufficiently insignificant to me.
As for the Dead, they were such an obvious choice for me to add because the list IMHO looked so empty without them. :-)
