Very overrated band. They're just another boy band for me, insanely popular for the 'mania', not the music.
Apart from The Beach Boys, there isn't one other "boys band" with a single album in the Top 10 of an all-time poll by a major institution (ex.
Rolling Stone magazine, Village Voice Pazz & Jop, NME, Spin, Pitchfork, etc). Hell, you won't see groups like the Backstreet Boys make a Top 10 for a year, much less a decade or all-time.
The Beatles have half a dozen albums in the Top 25 of most all-time lists. Even the wide world of hipsters across the internet, consisting of mostly GenX and younger voters, put more Beatles albums in its Top 25 all-time (x3) than any other individual or group. This on websites like RYM.
Beach Boys, Pink Floyd, Led Zeppelin, Velvet Underground, Bob Dylan, David Bowie, Queen, The Who, CCR, The Eagles, Wu-Tang Clan....doesn't matter. Nobody else can compete.
It's very much about the music. That's why they endure. Nobody remembers the "mania" except women with names like Agatha or Agnes.
