"21 sold 18 million globally in 2011 and 8.3 million the following year"
You trying to make the dumbest post of the year?
NSync sold 1.8 million in their debut first week. Wasn't mixed on headphones. Does that mean I should care?
250 Million sold by Rihanna... not mixed on headphones I would bet and should I care? Hell no... Does that mean Rihanna's music is genius and her mixing/mastering is incredible?
Eminem over 200 million sold and everyone can say his music mixing and mastering was and is horrendous. Definitely was tuned for apple earbuds and cheap car audio.
My favorite album is Eric Clapton's Slow Hand and if that dude mixed or mastered that album, I can only imagine how much worse and awful it was, probably cause he uses headphones exclusively.
I'm almost vomitting with the thought of listening to Layla with Adele mixing.
