Galaxy S6 when streaming Cumulus Radio station and charging

I use the iHeart Radio app a lot for music and listening to sports radio stations. I have noticed that when I listen to Cumulus Radio stations and place my phone on the Samsung wireless charging pad, the phone locks up immediately and requires a restart. I can listen to other stations on iHeart Radio with no problems. I even tried downloading the app for the radio station and got the same results. I'm also using LG Tone Pro bluetooth headsets. Any ideas?
