That I could believe. Sad thing is how it wasn't always that way.

it's absolutely always been that way
musical art has always been overshadowed by easily consumed trash and fad-followers, since the middle ages at least
especially when the church was stomping down anyone who did anything new/'threatening'/secular with music
Bach was known only as a skilled keyboardist and barely at all as a composer until a hundred years after his death
Mozart's somewhat low-brow compositions still dominate popular classical music
especially with the rise of romanticism - - thinking of Schubert, who died unknown and destitute, among others now superstars
jumping ahead among my grandparent's generation most people were tuning in weekly to derivative drivel like Lawrence Welk while the hipsters were speeding around the country listening to bebop and other 'real' music
Sure there may be periods with somewhat more crossover between legitimately artistic music and lowest-common-denominator mush, but if there are, we're definitely living in one of those good periods right now.
