He said it's easy to get paid. You just agreed with him when you said they are simple to make. You said "doesn't matter how long it takes, as long as it sounds good." So if a beat is, as jtraxx says, a loop with 5 minute of drum programming and some random bs, then it was EASY. The main reason those beats sell is cause they have a name or a look to sell. Neptunes produced it? Sh1t, it MUST be hot. Missy rapped on it? Shlt, it MUST be dope.
And the argument about Pac...please. That has nothing to do with it. Pac was talented, that's why he could write so quickly. Neptunes can make a more complex beat that may not get as much criticism, but it would probably take them longer. In beats, time usually is proportional to complexity (and I am not saying a beat has to be complex for it to be good). I'll give you 5 mins and I'm sure you can't recreate Human Nature, but you could recreate Grindin in that time.
And he dissed some beats. Making beats isn't just cause you want to fit in with everyone else... maybe there's something about hip hop they don't like, or feel they can improve and that's why they are making their own stuff. So as long as you are trying to do your own thing, you can say what you want about hip hop. Mos Def said we are hip hop. So if we are hip hop, then surely we can try and make ourselves better.
