If that is talent...we’re in trouble....
I have been a musician for more than 50 years, graduated magna cum laude from the world renowned Berklee College of Music in Boston, been a professional theater music director, a recording producer/arranger, a booker of musicians for various gigs. I have done many hundreds of gigs and played rock, jazz, theater and function music.
My late girlfriend, with whom I shared a breathtakingly joyful mutual immersion in music, was a world renowned professional classical viola player who performed at many of the world' great performing venues (i.e. Lincoln Center, Carnegie Hall), performed for 30-years with an award winning string quartet with more than 30 CDs to its credit (available on Amazon) played as a guest artist with the Boston Symphony Orchestra (among others), was in the orchestra that recorded John Williams' soundtrack for Saving Private Ryan, and headed the music department at a well-known Boston area university. Through her I attended dozens of classical music concerts, and met and interacted with many of the world's finest classical players and composers living today.
So with all due respect, I am very confident in my ability to recognize talent when I see and hear it.
If you want to say that you don't care for Bruno Mars' music, that's certainly legitimate. There are many brilliant and famous jazz and classical musicians whose brilliance is undeniable, even though I don't really dig their taste and don't really care for their music.
So if you don't like Bruno Mars, that's one thing. But if after watching his performance at the Super Bowl you think he has no talent, well, with all due respect, I think your opinion about that is pretty worthless.
