A few things:
1. I think the term you are looking for is Trap Beats, not Jeezy Beats
2. This guy is trying to sell them loop packs with the enthusiasm of them nikkas who be trying to sell you some pyramid scheme shyt
3. He is making a beat from a loop with multiple sounds in it where he has access to control the pitch and mute/unmute each individual sound. That is essentially a shortcut to making beats. All he has to do is add percussion. The hard part (constructing the melody) has already been done. It's even easier than sampling, because when you sample, you can't control every sound that is in the sample. You have to use advanced mixing techniques to "bring out" or "reel in" certain instruments.
4. That beat was not a "banger" as he called it. The drums, and particularly the snare, was really weak for a trap beat.
5. People like to shyt on trap producers, but that shyt is not easy as people make it seem. The concept is easy, but the actual execution of the concept takes skill. I make sample based beats, but making a trap shyt has always been a little difficult to me. I can make some trap type shyt, but not on the level of Lex Luger, Zaytoven, Young Chop, etc... It's not my style of producing, but I respect the skill involved in making it.
In closing, just because you have a lot of 18 year old kids who have mastered FL Studios and can bang out Trap Beats at a high rate doesn't mean that it is easy. They had to put in work and hone their craft, some just pick it up faster than others, and many never pick it up at all. I challenge anyone who thinks it's easy to break out your Machine/MPC or download FL and give it a shot.
If you are gonna use multiple instrument loop packs to make a beat, then you essentially are co-producing some shyt. Not to say it's wrong to do so, but I don't think you have the right to brag about how easy some shyt is when you basically have someone holding your hand/doing half of the work for you. It's like bragging about how easy it is to dunk, when you playing on an 8 foot goal
