I own and listen to a great deal of Chill-Out, Downtempo compilations. My main problem with any compilation is when they decide to 'merge' or mix the tracks together. This is fine with uptempo dance music where a beat-matching DJ mix is essential for the momentum, but NOT necessarily with Chill music.
"Soft" mixed is basically just the fading of one track into the next; as the next tracks is playing you can still hear some of the previous track. I guess by soft they mean that the 'overlay' is very slight - about a second or two. This violates the integrity of each song and is unacceptable. If we ONLY & ALWAYS listen to the entire CD from start to finish, then this maybe tolerable, BUT we all know that we have our favorite tracks which we prefer over the others - so we often skip to them. But now we can't properly hear 'the' song we like - we also have to listen to another song that's adjacent.
The problem worsens if you set the CD Player on random or if import the CD into iTunes. The integrity of each song is ruined. Speaking of iTunes, the 'soft' mixing they so graciously do for us on the CD is the exact same thing anyone can achieve with the softwares 'crossfade' preference. Mixing the tracks on any compilation is never a good idea; I wish the idiots who decide this would realize it! In fact, more Labels of these compilations should plainly inform us if the CD is mixed or not. Amazon should include this in the 'Product Details' or 'Description'. Beatport.com does this and I applaud them for it.
As for the "Comfort Zone" series - it is in my opinion one of the better Chill compilations out there. Their song selection is always excellent (no fillers) - if you're into great electronic Trip-Hop and Downtempo. They also always give an almost full 80 minutes worth of music. I'd rate this issue (#7) 5-Stars if it wasn't mixed. Comfort Zone 1, Comfort Zone, Vol. 1; 2, Comfort Zone V.2; and 3, Comfort Zone 3 are the best because they are Not mixed. Starting with issue 4, they suddenly decided to insult us by 'soft-mixing'...
