Hmmm.
I love my 70-80min! The so-called Double Album rules, in my life. 😂
To each their own, of course.
In rock/pop, I adore The White Album, Exile On Main St, nearly everything by Lana Del Rey 😂, Haley Williams last one, Dylan's Time Out Of Mind, etc.
Of course there are many 40min that I adore, but for whatever reason, the great 75min are my favs.
And, I'm the same in Noise! Vomir's 75min walls, Killer Bug's 2CD, Sissy's Mechanical Abstraction, etc etc. (I could make a long list.)
Again, I have many 30-40min Noise albums, which I love.
But 75min is where my brain really thrives! I dunno why.
