If the lower dynamic range tracks sound louder even after normalization then the normalization algorithm is flawed. ReplayGain weights the energy by frequency to better match perceived loudness, and it does a reasonably good job. Other algorithms might do an even better job at matching human perception.

Listen to this: https://soundcloud.com/amp-33/sets/uncompressed-vs-compressed https://soundcloud.com/amp-33/sets/uncompressed-vs-compresse... Those two things have a pretty similar loudness(A-weighted RMS) and yet the compressed one sounds louder than the measured difference - ~3dB A-weighted which is not obvious to perceive untrained. As a test - download them both, amplify the Uncompressed one at -2.7dB and listen to them again. They have the same A-weighted RMS yet the Uncompressed one sounds louder.
