Tchaikovsky's 5th is going to see a rise in popularity, I'm sure.
I don't know much about classical music, but I do know about rock and country before they became so commercialized. There were many a song that could bring a tear to a grown man's eye, and songs were made specifically to emit those kinds of emotions. Highly sensitive people just ate it up, so artists kept it coming.
Like the old saying goes: "Music has charms to soothe a savage breast."
