The 90s Catherine had the name first, the newer (and frankly) lesser catherine stole it without researching first if there was a previous band, so it's a no-brainer that the first band has the right to the image on last.fm...
I miss this band. Ever since this new, "metalcore" band of the same name emerged, people have been unnecessarily flagging images of this band, thus making them even more unknown
It works on a similar principle:
I say "My Bloody Valentine" (80s band), they think "Bullet For My Valentine" (new-age band)
I say "Blink" (original; from Ireland) they think "Blink"(182)
And practically no one knows that Puddle of Mudd actually *were* a grunge band
