I don’t find MP3Gain to be either a hassle or slow. Yes, if you are running MP3Gain on a large number of albums, it will take time. But it’s only done once–just leave it running overnight. For just a single or a few albums at a time, it’s done in very little time.
To each his own; it is good to have choices. For those happy with MP3Gain, stay with it. I am just trying to point out to those that use Foobar2000 that it works really well also.
Absolutely. I just started with MP3Gain with my main player because it didn’t have ReplayGain capability. I like the fact that MP3Gain’ed files are playable on any player.
