My newest song obsession

Normally when I listen to songs, I get hooked on them. Well most of the songs that I like are instrumental, like anime music by Shiro Sagisu, Toshiro Masuda and many others. But then there are some songs that have lyrics that I get addicted to, like Again by Yui, and Shoujo S by SCANADAL. But the newest song added to my addict list is Until The Whole World Hears by CastingCrowns. I'll post the video so you can listen to it,

So what's your newest obsession?

God bless
