ITT: people who have severely underestimated Mozart's musical capacities and contributions.
Mozart is a musician that is studied by nearly any professional musician. There are historians, musical scholars, and museums dedicated to him. He's a household name across the world. He established a period of music. As a teenager, he deciphered a 12 min choral piece with multiple groups and solos after hearing it once and by memory wrote it down later that night (he heard it a 2nd time a few days later for minor corrections). When he presented the score to the clergy, they said he got one note wrong. After investigation, Mozart heard it right. The musician's score was off by a note. Could any popular musician mentioned here decipher just a 6 min song of 4 instrument band after hearing it once with pen and paper ready? Imagine telling any music legend now, "Hey, you're off by a half a step on the 3rd note of bar 28 of your own song."
Comparing an awesome popular singer, guitarist, or band to him is like comparing your friend that got a job at NASA to Einstein. There is no modern Mozart. There have been greats since Mozart, but there haven't been any Mozarts since Mozart. I say this as a Beethoven fan. Mozart was the only Mozart. He was so good, that his name became a title for great musician: Mozart. No one listed in this thread is anywhere near being a Mozart.
