Reset iCloud Music Library

Hello All, I have had this issue for more then a year and can’t seem to get a fix for it so I figured I through it go the experts... if your up for the challenge. I have a Apple Music subscription and I use iCloud music library as is required and I have 5 device’s signed in. I used a iPod a few times to play music a my brothers party’s and my Apple Music subscription was used for the music. He likes country music and so that’s what was played at the party’s. These party’s last a few hours so i would guess about 500 played songs of country music in a continued loop a few times. Now with the music app expanding into curated music playlist I would like to use them if I could. But no matter what I do the “favorite’s playlist” only has country music in it. Or I’ll ask Siri to play music and what do I get, country music. I listen to more main stream hip-hop and pop yet I’d didn’t think I like that music. How do I reset my iCloud music Library? How can I clear play history? How can I get away from this music nightmare? I would love an answer! PLEASE HELP I know I’m not alone!
