Despite to be a top of "Modern Girls of the 80s" (all-female top), it features a male singer in the countdown: Prince: U Got the Look (1987).
The Top 40 hasn't host to introduce the music videos, and it hasn't opening or ending credits. It only broadcasts the music videos in countdown without pause or commercials but a brief channel ident promo each 20-30 minutes. In addition, it shows titles (solo singer/music band, song name and album name) at the start and ending of each one, and its number in the countdown.
Of the 40 music videos featured in the countdown, none is in black and white. Swing Out Sister: Breakout (1986), Eighth Wonder: I'm Not Scared (1988), Lisa Stansfield: All Around the World (1989) and Martika: I Feel the Earth Move (1989) alternate color with black and white. The rest of the music videos are in color.
In the countdown there is featured no one duet (understood as two singers and/or music bands whose usually don't sing together). Mel & Kim doesn't counts since that it was a musical duo, not a duet (i.e.: when Michael Jackson and Paul McCartney singing "Say Say Say" in 1983).
