I'm surprised rich thought this had a lasting value of 9.5. I couldn't listen to music without vocals for very long.
Its all a matter of opinion. I dont really need vocals and they dont play a big part in music for me, so for me I dont mind listening to it over and over again (as I have been for weeks now). For some people it will be a turn off, but for me I think it still sounds great and is a good listen. Its all a matter of taste.
