I noticed that last night when I came up to North Texas to see family. I thought it strange, but assumed it a technical glitch that would eventually get fixed. Today however, the song continued, and I meant to report here.....
However, an hour or so I checked and the station has returned to normal, the way it was before the repeating song. Seems they had the song on repeat or something. I guess they were finally made aware of the problem, and have fixed it.
It proves they don't care when big problems go that long unnoticed.
