C'Mon, GT&GO...
FIVE THOUSAND SONGS? In the "broad" era covered by the True Oldies Channel, say, 1957-1977, I'm not even sure there were five thousand charted records in the Top 100! And the focus of the format is about 1965-1975. The songs outside of that range are "flavor" for the format.
I don't know whose Kool-aid you're drinking, but somewhere in the neighborhood of 1500-1600 songs sounds more feasible. And that number comes from a conversation I had with the creator of the format itself, Scott Shannon. There are probably somewhere in the neighborhood of 600-700 songs that get a regular rotation (about 250 of those would be considered "Power Gold" or "Secondary", and the rest are songs in Scott's collection that he drags out from time to time as an "oh-wow" selection; I'm not even sure you could consider them "lunars", because they get played far less frequently than monthly). He especially does a lot of that nowadays in the middle of the day, when he's live/VT'd in markets like Atlanta and Chicago (Forgotten 45, Instrumental of the Day, occasionally a listener email request that's out of the norm).
I can pretty much assure you that if Scott were programming 5,000 songs, 1) he'd be pulling his hair out trying to make THAT work, and 2) the TOC would sound like -- to borrow a phrase from a frequent poster on the GA board -- "dog squeeze". Scott's not a dog-squeeze kind of programmer, but what he does well is giving off the appearance to the non-educated about radio that he's indeed playing thousands and thousands of songs. It's really just smoke and mirrors. How many snippets of songs show up in his "Calendar" and "Time Machine" features that you NEVER actually hear played all the way through on the station? Quite a few. I really don't think that Farid Suleman at Citadel would cram a crappy product that's so wide and deep as you're suggesting down the throats of MAJOR MARKET radio stations, regardless of how much power he has.
Oh, and for the record, I'm PD (read that as babysitter) for a TOC affiliate. I see the music logs for the format every day. And I'm also an experienced Oldies programmer who ran a very successful (from a ratings standpoint) Oldies station. So I know a little bit about the format.
