If There is an overlap might be late 70's-80's, but 1490 will be using the feed from westwood one. The range is from 60's-80's top 40 style like KJIN was back from 1971-1982. Before the station went silent for upgrades, they had the format on the air. I heard Music played that have not been on the radio in years. According to the station manager at My Home Team Media Houma is that KXOR's Music library is revolving to where more songs from the 2000+ are being added, but remember KXOR is a classic rock station, where KJIN is now a Classic hits (classic top-40) Oldies station. Yes there might be some overlap, but not enough to cause a conflict. I mean for example you won't hear any songs by Herb Alpert, Chuck Magione, Stevie Wonder, or Rupert Holmes on KXOR' but will be on KJIN.
