You have also got to remember that Pet Sounds was originally recorded on analogue (probably valve) equipment and equalised for the average hi fi at the time ie A mono dansette with a saphire stylus, then it has been re mastered in digital format which isnt the kindest thing to do, then converting a mono recording to stereo would account for further degredation.
At the end of the day, its about the music, not the playback quality, but poor sound quality can be a distraction.
Dont like The Beatles either eh ?
Right heres a quiz, write down as many Beatles songs as you can, then do the same with Interpol. No cheating, all from memory.
Give me an honest answer ! how many?
Also, how many Beatles albums have you listened to, not just heard the odd track ? and Yes, they did write some crap as well, strangely, I can also remember those tracks.
The Beatles influenced and is influencing generations of rock bands, very few escape.
