hi im super new to osu and i was wondering if you guys can help me figure out how to music to my osu

maps from beatmapsets
you should be able to import them into osu by just clicking on the ed .osz file or dragging the file into/onto osu! via the game window or the desktop icon.

pretty much what the person above said

that being said, if you're looking for the possibility of "ing" specific music you yourself like to osu! (since I'm getting kinda that vibes from the opening post as well), that's not exactly possible straightforward like that. Beatmaps in osu! are manual, -based effort, so they won't just happen on their own. If you're interested in that (aka mapping), you can start by giving the respective wiki a look. That being said, being super new, it's probably better you get a bit more familiar with the gameplay and game itself before diving to the deep end

does anyone know how to play a song that is not on osu?

your options are ask someone to chart it for you or, optimally, chart it yourself

There are also people that do mapping for a small bit of money i think

This is a necro, but since there's no s here, I'll count that as a normal thread

I saw a few mappers doing that on Twitch for example
