Is the volume high enough in the fuze after applying replay gain to tracks?

Is the volume high enough in the fuze after applying replay gain to tracks?I noticed that the volume decreases after analyzing volume.

Thanks,

ReplayGain uses an 89dB reference level.  Most major label music produced in recent years is actually compressed and boosted to the point of clipping.  In this case, ReplayGain would reduce the level.  For older material recorded at lower levels, the gain would get boosted.
