Radio Station Play lists How many songs?

How many songs do most music radio stations have in rotation?

Top 40 stations probably have fewer than a classic rock station, but do they only have 40 songs in rotation?

Back during the early 90’s, the local classic rock station in my town used to boast it had 1000 songs in its music library and occasionally even set aside a few days to play it’s “Top 1000 of All Time.”

Of course this was a few years before people started storing thousands of songs in their computer hard drives and MP3 players. Saying your music library has 1000 songs now seems rather underwhelming.
