I'm really starting to think "Eternity" is VIXX's best title yet.
Excellent production, smooth but with an edge (the "oh woah"s in the chorus aren't too polished).
The pre-choruses are so awesome, and I like how they're both different from each other. Hyuk and Hongbin both killed the first one while Ken's repeat/breakdown part for the second is a nice climactic moment.

Also, there isn't too much Rrrrravi. Love the dude but he can overdo it sometimes, so I'm glad his part is small and compact within a song that's already doing a lot.
Definitely their best single album yet, the other two tracks are great. They're only getting better!
