"""I always fear hearing the other guy's song on the radio louder than mine. """
well i got this one track on the radio right now that is quite a bit lower [-19dBFS RMS] than modern albums, not even "mastered" but on the radio sounds just as loud as everything else. go figure

i also have two other songs from two different HEAVY bands, one is mastered and fairly hot [althouigh WAY too bassy, it was the bassists fault

more me syndrome] and the other is unmastered and both loudness sound similar coming off the station into my receiver.
about that weezer cd, its really weird. hash pipe sounds great but every song after it basically sounds like they got the levels for one song and let it run with the same mix for the rest of the program. i just listen to it and get mad because i hear so many things that could of made the songs so much cooler.
same thing happens on the new black crowes. the songs CLA mixed sound like doo doo compared to the don was mixing team... although that album is a major disappointment [but i have some friends who LOVE it], just so uninspired to me. im starting to think the BC were a fluke with SHAMC being their only great cd. amorica is okay, the first one is mediocre. i think the two brothers fighting is more interesting than their music.
but it certainly is difficult these days with modern CD's... my tastes span time and genres that in a cd changer on random, the levels are OBSCENELY different. do you really want to be the one with the "quieter" cd?
another thing i notice besides the radio is that the louder cd's dont crank up the volume as well. they sound better at lower volumes IMO but totally lose out to more dynamic ones at loud volumes.
