What do the scores of 72.50 and 68.20 mean exactly?
I have seen some confusion on this board about those scores. Some seem to be confusing these scores with callout numbers. I hope I am not stepping on anyone's toes if I answer this question. I worked in radio as a program director *hangs head in shame* for a number of years and still occasionally DJ when one of the "regulars" in any of four local stations goes on vacation or is unexpectedly absent. I have been able to "spin" TOML on several occasions but have not filled in for anyone since LO was released. May as well share the knowledge, right?
These scores are from the Mediabase/BDS-affiliated HitPredictor.
To explain the difference between HitPredictor and callout:
HitPredictor scores are compiled from a website called Promosquad. Anyone can join Promosquad. And here is what they do: When a label is considering sending a song to radio as a single, they first send the song to Promosquad to see how it performs in a "focus group" environment. When a person signs up for Promosquad, they select what type or types of music they are interested in (these are based on radio format, like CHR/pop, Alternative, HAC, country, modern rock, etc.). When Promosquad has accumulated enough potential singles from labels (anywhere from 10 to 20) in a given format, they send an email to those who signed up in that format, asking them to come listen to the "jukebox" and rate the songs. The beauty of Promosquad (unlike ratethemusic.com where you can just vote without listening, multiple times) is that the listener can't skip through songs. In other words, you can't go on there simply for the purpose of rating a favorite (they may not even show up in your jukebox). And, sometimes, the artist isn't named (you are simply hearing the song). After each song, you give it a score from 1 to 100. After a period of one or two weeks, Promosquad compiles the average score for each song in a given format and sends them to HitPredictor for publication to the radio industry. Songs must have an average of 65 or better to be considered as having hit potential and therefore be listed. These scores are based on popularity on initial listen, not familiarity. HitPredictor is usually what will get a major market (and by extension, smaller markets) to play a song (especially if the label isn't doing too much in terms of promo push). So, the scores that LO received indicate that it has hit potential in both CHR/pop with an average score of 68.2 and HAC with an average score of 72.5. (It is disturbing somewhat to note that Archie is referred to as the AI winner on HitPredictor, because this indicates that 19/Jive is sending his music to Promosquad with that notation. RCA is not making that distinction with DC, which is fine (good, even). But, if he doesn't get that distinction, no one else should. It's bad enough that everything from album release schedule to video release to single promotion has been handled as if DC were the runner up, but I am getting off topic.)
Callout, on the other hand, is something entirely different (although it involves the number 65, which might be the cause of any confusion). When a single is on a radio station's playlist (or about to be) it will be included on their station's music survey (usually updated weekly). People who belong to a station's music panel then take the survery. They are asked three questions: Are you familiar with this song? (They are asked to listen to it if it is unfamiliar to them.) Rate this song from 1 to 4. Are you tired of this song?
A song must have a 65% familiarity in order to be included in a station's final callout tally. The scores are then averaged and the songs are placed in order from highest to lowest average score. The average of people who respond that they are tired of a particular song is deducted from the song's score to give the final result. The final results from all monitored stations are then sent to Mediabase and/or Arbitron BDS to be added together and averaged to show the national callout scores. For example, in the nationwide callout score from 10/9, TOML ranks at #1 on AC with a score of: 79.9 familiarity, 75.9 positive feedback, 11.6 negative feedback and 6.5 burn (tired of it). These scores are readily available for public consumption (to those who know they exist) at allaccess.com. Callout scores generally help formats determine which songs should be getting more airplay (and which should be getting less). Also, if a song is ranking high on national callout and it isn't even on a station's playlist, it usually gets added. Callout scores tend to be far more reliable than ratethemusic.com because each participant can only take the survey once. Some more rabid fans do attempt multiple surveys but the final tally takes into account IP address (not just email) so multiples are thrown out. (This expains why "Crush" is #1 across the board on ratethemusic.com in AC, HAC and CHR/pop but only appears on one callout list - at #11 in CHR/pop.)
Of course, every station (and program director) is different. Not everyone uses these industry tools in the way they were intended (some pay them no mind at all). But, in general, my mini-novel (sorry about that) sums up exactly what these things are meant to do and what the various scores mean.
However, always keep in mind that some labels have significant influence and sway over program directors in certain formats (i.e. Jive in pop, Arista in R&B, Roadrunner in rock, etc.) and major markets have a tendency to go "where the money is". Smaller markets, in an effort to be seen as up-to-date and current also have a tendency to do what the "big boys" are doing. So, while stations in general will at least give some credence to HitPredictor and callout (not necessarily ratethemusic.com as it has become a joke in recent years) and give a chance to songs that the public is actually saying it wants to hear, the "big boys" (start in New York and follow the trail) and the label giants to which they adhere still, sadly, play a much larger role in determining what gets played, when it gets played, and how much it gets played.
Sorry for the novel-like explanation, but I think this information will be beneficial to those who are following the radio progress of DC's songs (and the inevitable questions that arise).
