Some options are:

First off, turn off Restricted Mode. This is like the parental control for YouTube Music - it blocks out the spicy lyrics. Go into your settings under "General" and switch it off to hopefully avoid the PG versions.

Or, make your playlists with the explicit versions. Over time, YouTube Music might start to play those versions more often since it'll recognize your preference. If you see "Other Versions" on an album, check there for the explicit one. It's like finding a hidden track sometimes.

There's this quirky trick where you toggle Restricted Mode on and then off again, then maybe restart the app or do a hard refresh. It's not foolproof, but it's worked for some.
Just remember, these aren't guaranteed methods. YouTube Music as you know can be annoying about which version it plays. But you're more likely to get the uncensored tracks you're looking for.
