Every album I’ve ever encountered seems to have a mixture of bangers and one or more meh or outright flops. It’s easier than ever to skip over the tracks now, but as the question asks: what’s is, in your opinion, the perfect album, or does one/can one even exist?
As other have said, it’s subjective, but here are some albums I’d consider perfect:
Blue Lines over Mezzanine? I usually mention Mezzanine in threads like this because the fact it was released in 1998 really doesn’t come across at all.
Every day of the week - don’t get me wrong, Mezzanine is great, but for me Blue Lines is absolute perfection :-)
