Yes, I believe that both 93.7 KGSG and 104.3 KHTR are using stolen downloaded MP3 copies. If they had purchased them on iTunes, they would have been better quality. It's really too bad that these stations didn't spend a few more bucks to purchase full quality wav files from TM Studios. The small price would have been well worth it.
I don't understand how station owners can spend thousands of dollars on state of the art audio processors, and then play low quality MP3 files. It's like taking a bottle of pure spring water, and then mixing in a handful of dirt, before drinking it. It makes no sense.
Respectfully, xpert, you don't know what you are talking about.
The KHTR music comes from one of the major, well regarded, radio music suppliers.
