Why do people like Radiohead?

ATTENTION: THIS IS NOT A TROLL THREAD!

I genuinely want to know what it is about this band that attracts so many people to them, because they have absolutely no appeal to me. With most bands that I don't like, I can see how some people could like them, but for Radiohead, I just don't see it.

For example, take this song by them:

and tell me what it is that you like about it, and maybe I'll be able to get it.

Don't just give snide answers like, "CUZ I SMOKE A LOT OF WEED, AND DEH SOUND GOOD WIT WEED!"

How can you be hostile toward a musician because you don't think they're that good?  Do you walk into furniture stores and say to random customers, "HEY ASSHOLE, THAT SOFA IS TOO DARK, WHY WOULD YOU BUY THAT SHIT YOU FAGGOT?".
