3 Years of Service
I don't care because I always turn it off. And I don't mean just porn games, but all games in general. Developers always put the music volume at 100% which with 38W output power of the subwoofer (trust me, that's a lot more powerful than you think, especially with ALSA and proper equalizer settings) feels like someone's ringing a giant church bell next to my ears. So the first chance I get I turn all music off. Then, if I decide I'm interested in the music, I either unpack the game and extract the music manually (if it's a renpy game or any other kind of open source game), or if it's a closed source game, I usually search in YouTube. That's how (by a YouTube search) I discovered I liked some of the music of "Saints Row The Third" with "Killbane and the Syndicate" being my favorite track.
