One day (if you want to, I’m only sharing my opinion), you should try Stark+SS or Khan, both those mix are amazing for sales (for me).
But yeah, influencing people isn’t dependent if you are easy or not to influence
Selling is more of a communication. You need to understand what the other person wants and from there, guide them on how their product can help them with what they want.
Edit : @King I just realised, PS contains Sex&Seduction so… I guess it would be good for sales too 
So if I would try to sell you PS, depending of your goals, PS might help some of your need (are there any more goals that PS could help you with?). Then I would see, do you have something to lose by running PS? I need to evaluate what it cost you to run this sub I am recommanding! We are talking about time (how much efforta is it to purchase, add it to your playlist, listen to it…), do you have to reduce your exposure to other subs? Are there any adverse effects that would discourage you to run PS?
Then once the logic side is dealt with, I would use my charisma to pump you up just enough so you purchase it
, and then it’s up to you.
This is straigth from the straigth line salea system from Jordan Belfort that I applied at the bank. I have slashed a couple of steps I think, but it’s been effective for me
I learned all of this while listening to Khan, I was checking the audiobook and talking notes to get better at sales and get my numbers up. Turn’s out, I’m an amazing salesman… I don’t tell it often here on subclub, but my sales game is very very high.
