Possible doesn't work in lore but consider:
Drifter with a music working playlist
Drifter having some kind of mp3 player, or maybe just blasting the somacord. Starts off as a way to drown out the Angel Song, give them something to focus on, and makes walking around the Zariman feel less lonely and maybe even fun.
As time homes on, it becomes a habit.
Drifter playing softer music when sneaking around to free prisoners.
Drifter blasting music when fighting the Archons.
Anyway flashward to when Drifter is in 1999, basting music during missions through their comlink.
Bonus, totally not imaging this with early 2000's music either.
