Find music for youtube shorts

I really like the music used by youtuber dwarkesh patel in his youtube shorts. i want to someone to either find the songs that he uses or find songs very similar. i need to be able to licence the music too, so i can use them in my youtube shorts, and obviously i will pay for the licence. happy to negotiate fee based on how many songs you can find. ive spent 4 hours already looking through a lot of music databases and havent really found the right ones.. here are some of the songs i like, but any dwarkesh uses are probably good; https://www.youtube.com/shorts/qEXHbJzGrY8 https://www.youtube.com/shorts/mJE5s8RmvRI https://www.youtube.com/shorts/srET3ahp0ns https://www.youtube.com/shorts/l69nxm9dFT4
