no way is it the beatles, they were truly revolutionary and deserve all the merits they get
They were the defining sound of the 60's and released Sgt. Peppers, the first rock album.
U2, yeah they're not all that great.
Coldplay are definitely overrated,
Oasis, like the beatles, defined their era and I'm a big fan of their style.
For me, the most overrated band/artist of all time would have to be Dylan...
does he count? If not then I'd say Bryan Adams 😛
Bryan Adams got up off his butt after the 2005 Pakistan earthquake, flew to Karachi in January 2006 and did a benefit concert in front of ten thousand enthusisastic Pakistani teenagers. I'd say he was certainly underrated for that very fine effort. As far as his music, well I give you that it rocks in an utterly predictable way, I do well like about six or seven of his Anthology tracks as samples of trad rNr. I play them in the car and they're like a summer day brought back complete with its fresh air.
On Dylan: he is not overrated. Erratic, yes. That's art for ya.
U2: the band, its musical output and ongoing evolution are not overrated. The focus on Bono is irritating. Bono did once thank his bandmates for "letting me sing in yer band..." I'd like it if Bono's VIDEO PRODUCERS would remember that from time to time, sheesh.
Oasis rising was something wondrous. After that, I dunno, are we still holding our breath or making excuses or have we (and their dreams) moved on?
Coldplay: verdict not in. They are still in ascendancy, I think. Their output so far includes some extremely well written, well performed, well produced music, worth putting the existing discs on repeat while waiting for the next one to show up. I don't care how many or few million copies were bought. Overrated to me means "given more credit than is musically deserved." Coldplay are not, by that standard, overrated.
Beatles: I just don't know. I didn't hear them when they were all the rage, I was still buried in preclassical motets and masses. When I did hear them, I heard them AFTER i'd learned to appreciate a lot of blues singers plus a smash-and-grab assortment of rockers. (I had smashed my way into my brothers' collections and grabbed everything they would let me borrow, and there was a pile of blues rock and edges of metal). Perhaps I heard the Beatles first as a little fey. Then later on I discovered alt rock and decided fey was a passé term, or at least not right to stick on a band like the Beatles! Their catalog has not really won me over but their influence in Brit rock has persisted and for that I'm grateful; I get a kick out of the Brits still coming along.
