Request Google Music to support Replaygain
Reply #10 –
I have no love for Apple in this arena either, eschewing the established ReplayGain standard for their own less-flexible standard is a calculated move to increase vendor lock-in, with the added effect of slowing adoption of any volume normalization system.
Apple has had sound check for as long as I can remember. I don't know when Replaygain came into the scene, but I remember my third-generation iPod had sound check and I'd be willing to bet that at the time the competition didn't have anything like it. Also, it is almost as good as you can apply Replaygain values to the sound check tag.
Replaygain was proposed in 2001, which is the same year the first iPod was released. Speaking of the competition, I used a rockboxed iRiver H120 with RG support in 2004 or 2005, if memory serves me well. Using google the oldest mentions I found of Soundcheck and iPods are in 2004.
