Love of albums is a funny thing. I totally believe that to love an album and call it flawless is to love the imperfections too. It seems there is very few examples of perfection in this world, maybe none.
They say you love people not for their attributes, but their imperfections. Flawless albums end up being that way only because your mind becomes charmed to liking the mistakes.
A flawless album to me is the remaster of The Song Remains The Same by Led Zeppelin. I have a total of three versions. The 180 gram remaster vinyl, the remaster CD and the original vinyl from the day.
This album is full of said imperfections. The band said they were tired. It's a live album too. The reason I like it is it captures a time in music history really well. Some would say that Zep is overrated, some would say the recording is not perfect.
The end result is hearing it and the mental effect it has. The transportation element. If the music starts to seem timeless then that is also a helping factor.
