Subject: [PATCH] Fade music back in when returning from song select from
 gameplay

Addresses abrupt playback pointed out in
https://github.com/ppy/osu/discussions/34472.

In cases where the music is already playing, this isn't required (ie
when returning from the player loading screen before gameplay starts).
