Yeah Jayson, with Apple Music I noticed a difference in volume right away when playing music on my car. I also have iTunes Match and the same thing. This issue I mentioned above was actually something else. I believe it's happened a few times both in iOS 8.3 and 8.4 where the volume sounds like it's turned down almost completely. I check my volume on my phone and it's maxed out. In fact today it was low, went up and low again on its own. I'm not sure what caused it but turning the Bluetooth on and off doesn't fix it. I have to either reboot my phone or turn the radio off and back on. When I connect my phone to my Sienna it sometimes plays but skips the songs like a scratched cd. Strange stuff and I realize a lot of iOS 8 adopters have had several issues with their Bluetooth. I guess I'll keep an eye on it.
