Sampling in hip-hop will never die. Ever. The die-hard fans who were around in the Golden Age of hip-hop won't let it because its true to the roots. Its just a question whether or not it'll be in the mainstream. But I don't listen to a lot of mainstream rappers so I hear tons of sampled tracks and those are the ones I prefer simply because most beatmakers aren't able to create beats that have the same perception of depth. I think the mainstream rap trends will feed off whatever's popular in the pop genre. So keep an eye on that and you can get an idea of what's to come. I wouldn't focus so much on what the trends are because they're going to change anyway. They don't just come up out of thin air, someone starts em. So instead of focusing on what's popular now, focus on doing your own thing and who knows, it could become the next trend. But at this point, it seems almost every trend that could happen in hip-hop has happened and now we're recycling. The shit that's popular now ain't much different from the shit that was hot 15-20 years ago. I see that with a lot of these up and coming mixtape cats that are gaining hella buzz, they're starting to bring that 90's sound back again. Then you got trap music in the mainstream. Ain't much but some menacing sounding, two-note strings with some hard ass 808's really lol. But as much as I love hearing a nice soul sample, I try to refrain from using em since you really gotta dig to find ones that haven't been chopped to death. I'll sample anything though if it sounds right. I mean, shit, I made a beat sampling that Marimba ringtone from an iPhone and that came out pretty hot lol.
