I was never fond of remixes. Pure bonus tracks that are complete new songs or hidden tracks are cooler
It's a totally new experience. Sonic Syndicate has done it perfectly I'd say. They have tons of bonus tracks that it takes a while to discover if you weren't as lucky as to live in a country that released an album with the bonus tracks
and they had some hidden and unreleased bonus tracks around as well. Awesome! Keeps the love of the band fresh!
