In my sound settings, I have all instrument tracks as well as the song preview setting set to 100%. However, the song preview loudness is noticeable louder than the song when playing. For comparison, the song preview is at 76db and the song while playing is at 72db.
To be honest, for comparison I play at 80% of my master volume in Windows for Clone Hero, but in the nightly YARG, 100% of my master volume is still quieter than Clone Hero. I haven't tested this in stable.
Personally I wish YARG was louder when playing songs.
