I doubt it. 1911 we had Victrola/orchestra/ singing (around the time not everything was mozart instrumental orchestra stuff) music. 100 years later in 2011 we have upbeat/pop/synthesizer/dance music. 1811 we had Classical beethoven/mozart music. Every 100 years, artists and music change drastically (just like every 10 years, fashion changes drastically)
I'm sure in 100 years they'll know who madonna is, and lady gaga, and michael jackson, and blah blah blah, but no one is going to listen to them. I don't have my ipod filled up with tons of
this type of music which is from 100 years ago (1911). So I
highly doubt in 100 years, anyone is going to have our music floating around.
