Made in America was planned to publish as a single, it was a radio single but didn't get enough airplay to publish as a commercial single. I talked to Mercury Germany at that time and they said that a song is given to the radio stations 6 week prior the planned release for sale and if it will be released depends on the airplay. Only a very few radio stations played Richie's song so it was not enough.

There was already a video-clip filmed for this single, that was recorded at Richie's concert in Cologne but it never saw the light of the public.

Mr. Bluesman was a single, at least I have seen one at a record fair, it could be that it was only a promo for the radio stations though.

Not sure about One light burning, since there is a video for this song I guess it was published or at least planned to publish.
