wanting to see different artists from the group?

so i last minute decided to join a friends coachella group. got my tickets already and splitting an airbnb w them. total is gonna be 10 people but i only know 2 of them. anyways, im realizing we have very different music tastes i guess thats something we shouldve talked about in the beginning before i decided to join and thats on me. they were just very persistent about me going to join them and saying itd be fun. now im just conflicted because i dont want to be that bitch thats the only one that ditches the whole group but come on, they dont want to see gaga and thats fucking me uppppp. idk what the best move is bc im also not spending 1k+ to not see like my fave artists. im alrdy sacrificing not seeing other ones for them so i dont ditch the group
