Having spent a lotta time with the Billboard charts, I think sometimes it was just easier to write "all cuts" than list the main ones, especially if they have long titles and number more than 3...space was an issue --everything had to fit in that one column. They couldn't list 12 tracks by title and have it all fit.
Thus far, in the charts I've been compiling, towards the end of 1976--the "all cuts" LPs would mainly be the Salsoul Orchestra & Donna Summer LPs released to date. On both the Salsoul Orchestra LPs there is one ballad track that wouldn't count as a dance track--but rather than call attention to that one track...it was easier to write "all cuts"...however, one time on the first Salsoul Orch. LP they did write "all cuts--except "Love Letters"...but only once as far as I recall...
But later, on a multiple disc set containing numerous dance tracks, Like "Thank God It's Friday"...Billboard only charts 4 tracks: "Last Dance/After Dark/Thank God It's Friday/Take It To The Zoo"...when a number of other tracks were playable as well...so maybe they change their policy as time goes by...I think people wanted to see specific titles listed, not just generic "all cuts."
Regarding Sylvester's "Stars": I think Billboard listed the 3 uptempo tracks and while I know clubs like Trocadero played the downtempo (around 110 bpm) "I Need Somebody To Love Tonight"...maybe fewer clubs that didn't have a "morning/sleaze" time period would go that low in bpms, so that title was not reported...but some clubs certainly did.
So, in conclusion, I think the various factors were: efficiency in typing "all cuts," space limitations, different clubs having different taste, and different compilers having different ideas about how to do it.
