These band names belong to the nonsense/ nonsequitur band name genre. They seem to make no sense. Don't even try to think rationally about what a psychedelic fur is; it's not meant to be logically understood (but maybe it has something to do with Joseph and the Amazing Technicolor Dreamcoat).
I admire the Dada element in these names. Turns out that Pink Floyd does have a logical explanation: it's named after two blues musicians. More interesting is that Pink Floyd started out as Tea Set. Wow, is that ever a wussy name. It might be appropriate for Belle and Sebastian (and hey, I like B&S), but not for space/stoner rock.
Pink Floyd: 7.9
The Psychedelic Furs: 7.0
