I mean, just compare Music under Sequoia and Music in Tahoe. One is clearly easier to read than the other one. It is also far less distracting. I can tell you it isn't Music under Tahoe.
Who designed this and legit thought "This is so much better and people will have a far better time using it!!!"?
I鈥檝e been an iTunes user since 1.0 under Mac OS 9.x. This is the biggest UX regression in its entire 24 year history. Sigh.
