I really like PsyTrance and Goa. Search for „Astrix“ or „Ace Ventura“ (artists) + „ozora“ or „boom“ (festivals) on YouTube. I really like the speed of it and if there are lyrics, they are very repetitive / meditation like. Also the sets are quite long.
If you are in a workplace setting, try to keep the live sets in a background tab, as Goa/PsyTrance Festival recordings might have half naked people in them.
Edit: Or try to find artists in a genre you like, singing in a foreign language. I really like Korpiklaani, as don’t understand and probably never will understand a word of Finnish.
