Most people who listen soley to rap, couldn't even tell you what 4/4 is...haha I remember a story of when P. Diddy was working with Jimmy Page on the "Come with Me" track...Jimmy page said he wanted to modulate a note from a C to a D. P. Diddy replied, "I don't know what you mean with all the C and D talk."
haah, What's more sorry than the people making this shit, are the utter idiots who buy it. You put some kind of danceable beat to anything, most club going idiots will think it's "hot" and buy the record. Once an artist has a name, he can put out dog shit and the stoned guido club goers will think it's "amazing".
Missy Elliot: King of one bar loops.
Kayne West: Guy uses a pitch shifter on already classic songs
Mediocre shit always rises to the top. Granted, there aren't many good rock bands today either. I usually don't value anyones opinion on music, unless they actually know a little something about it.
For the past 12 years, it's been complete crap, always on the top of the charts. The whole hip hop thing is the worst thing to happen to music, since Kiss.
