Back in the early 90's, many people complained about two events that happened in music: Milli Vanilli lip-syncing and Vanilla Ice sampling Queen and David Bowie. The outrage that still goes on about these two events proves that today's "artists" are a bunch of hypocrites.
The Milli Vanilli incident. After they were caught lip-syncing, everyone and their mother, who was in some way involved with the recording industry, panned the duo. They were both run out of town and never heard from again. But these days, artists lip-syncing a song at a live performance is actually extremely common. I don't see the Grammy committee breaking any appointments to call a press conference and take away J-Lo's Grammys.
Vanilla Ice. To all the rappers out there today who call out people like Vanilla Ice, shame on you. How dare you criticize someone who, while even though his music still sucked in any case, sampled music beds from REAL artists of yesteryear. Sampling has become one of the most common practices in music today. It really is hypocrisy at it's finest.
Note: The fact that I am using these two musical acts as examples does not in any way, shape, or form imply that their music is, in fact, any good. Listening to either of these musical acts may result in a poor taste in music and/or friends.
