Well, I personally think they're not that great. They have a few songs I really, really like but after listening to their entire collection of crap many, many times, I can safely say, I don't think they're as good as everyone says they are, thus them being overrated. I'd even go as far as saying the majority of their fans are emo fuck twats. This opinion has been formed over the last two decades of dealing with wank stains like yourself praising them as the second coming of christ.
If you don't like them, that that is fair, you should have said that.
Overrated? Please, bunch of lads who never played music before, learning while making their first album is pretty big. Back then bands used to think they were the shit, playing some convoluted crap just because they were artistically ''knowledgeable''
Joy Division laid out the fundamentals of Independently making and releasing music even if you weren't a music maker. They were shit, sure, many thinks so. But simple riffs which can be layered into a very able, danceable music with little to no knowledge of music seems to be a big deal. Not to mention, they have created a whole genre by themselves that focuses on base and hallow drum, with morbid and politically fuelled lyrics.
They were funky without the funk, they were punk without the mindless shouting and rebel. They were Rock 'n Roll without the ''cool'' mentality. they were pop, without the mainstream help of radio and press. They were incredible without any production or engineering. They were artists without being artists.
You don't like their music, that is fair, many don't like them. Infact, I'll go as far and say they might be trash at playing ''music'' itself. But overrated because many people think so? GTFO with that bullshit, because, not only were they that important, but they were genuinely liked by many people for very genuinely reasons, and yes, they are fucking second coming of christ in music industry whether you like it or not.
