One of the interesting things about this station, besides being the most reliably copyable African national broadcaster I can copy, is that they will often (not always, but often) sign on early with some music before getting into their distinctive interval music and finally a nice "Nigeria!" at about the official 0600 sign on time. Tonight they're playing an American gospel tune. SIO 444. Actual frequency 7254.925 kHz. (It drifts around, but not much from day to day.)
EDIT: video of reception, per shazam the song was "God Is Good All The Time" by Don Moen.
