A pretty decent collection of Konami Originals from 1st to 5th, including some of the Club Version songs which were really deep cuts at the time, all wrapped in the 4th Mix engine. If only this was actually based on the 60 FPS 5th Mix engine like the logo suggests, but I guess it was easier for Konami to hack something together with 4th since they already did that with Extra Mix. A huge leap from the first US PS1 release, but it might be hard to go back to after experiencing the PS2 games.
