Cascada's remake of "What Hurts the Most" by Rascal Flatts?

What happened here? They did a remake of What Hurts the Most, one of the most awesome songs by Rascal Flatts, and made it all high and fast? That's terrible, totally wrecked it for Rascal Flatts. What Hurts The Most is one of my favorite songs and always has been since they released it, it's a sad, slow, beautiful song and then Cascada goes and makes it fast and high and frilly. I mean, I like Cascada but it totally wrecked the song. Any input on this?
