I can't help you with a list but one consideration is a list you get today may not be the same as it is in 6 months, a year or more. The way these music licensing groups get you is you pay their annual fee or devote the time and effort to track down their material and be sure not to play it. As they are adding songs on a regular basis, that list changes and you must stay up with it. For more, if you value the rime and effort, paying their fee winds up being cheaper. If your station doesn't have the money and they know it, they might not keep an eye on you. However, if you stop paying and slip up on a song and get caught, the result can be pretty substantial. You need to weigh all sides to determine if it is worth it to pay so much to play a few songs.
Maybe a call to SESAC about what product they license is in order. It would seem reasonable they could provide a list, even at a token fee.
