I may like the music slightly less but like I mention before rock music does have some clear advantage over classical music that can't make it a completely redundant genre of music.
Also my like classical music is based on the same principles that I judge pop/rock music. Listenability, emotional resonance, pacing, depth, timbre/atmosphere. Nothing has particularly change in my taste. The same thing that attracts me to pop music is the same thing that attracts me to classical music. A good melody in a Beatles song Touch the same area of my brain as a theme from Mozart or Tchaikovsky. A loud soft sudden shift when done by Radiohead/Nirvana/Pixies touch the same pleasures centre as a Beethoven sudden contrast shifts in his symphonies. A cool chord progression in a pop song is pleasuarable as is a harmonic changes In a development section of a classical music piece. Converting myself to classical music is just a logical extension of my pre-existing taste
It's just that the classical pieces do the same principles that attract me to pop music better.
If I went from it backwards of getting into pop music after classical music I may not have the same mindblowing epiphany of discovery new great music that I originally had when I heard the 5 star artist the first time but I would rate those music approximately the same way I do now
