^I live in the US, and I actually hear We Belong Together on the radio pretty often for a song released in 2005. The DJ's usually have something nice to say after that song, like "that brought Mariah back" etc. Her older songs I hear on the radio are usually I'll Be There, Hero, Always Be My Baby, and We Belong Together. Also, I've heard Don't Forget About Us a few times in the past months.
