It wouldn't surprise me if after playing the same thing every single day for 7 months, even the bands don't feel their own music.

I think Opeth fits into this category. They have a huge fanbase, but that leads them to have plenty of detractors. Why?

1.) Many metal fans hate any new metal band which is very popular.
2.) They simply do not understand Opeth. As elitist/snobbish as that may sound, it's true. If you have a band that fuses prog rock, psychedelia and death metal, you're going to come out with an unusual sound. The average death metal fan will think it's strange because he isn't accustomed to prog/psychedelia - he's judging a band which is a fusion of a few genres by the standards of one genre (dm). So, he's not going to understand what all the fuss is about and will probably react negatively.

That's my understanding of it anyway.

radiohead...

My Chemical Romance. Huuuge fanbase, mostly little girls who overrate them to extremes... then there's the many many haters.

Nickelback fit here. All dedicated music fans think they're the worst most insipid act in all recording history, while the general population almost can't live without them.

EDIT: But hang on, I don't think I'm getting the original point. This is meant to be about who is most overrated and underrated by real full-time music fans, isn't it. So maybe Nickelback and My Chemical Romance etc. don't count. Yeah, I reckon they don't.

Ah, now the psychedelia might not be instantly obvious, but Mikael Akerfeldt was quite influenced by psychedelia... he worships it. Like him, I scavenge around for the hidden psychedelic gems from 67-72. It plays quite an influence on his writing style, and you might not pick it up unless you listen to psychedelia. And that's the same with Per Wiberg... it's worth mentioning that he's also in Spiritual Beggars, a stoner doom band.

Blackwater Park itself is the name of an obscure psychedelia band.

easily, its MCR. i was so sick of hearing about them that i started to hate them. now that i have actually heard there music, i have decided that they are an OK or decent band

I think the most overrated is fall out boy's bassist

I actually exclude that Nirvana,or any other bands with the same style.

That's genre problem,I just dont like it
