OIC. Sorry for the cornfusion (Hoosier Humor!) I haven't noticed this. I don't even look at the order of the songs. I either play a group of CDs by the same Artist, and shuffle the songs, or just play all my songs shuffled. But, I do wish that there was a way to play a group of Artists; not just one at a time.
Since you have your songs on an iPhone, I'm guessing that you are using iTunes. Uconnect only supports iOS up to 7.1. I went crazy trying to use iTunes on this frigging radio (I want my MyGig back!) (I wonder how many times I have said this now! LOL). I loaded all my songs from iTunes to an SD card, and had a mess. I purchased a 64GB iPhone5S and put all my music on it so I could use it as an iPod. No dice. Same thing. I found an iPod with 7.1 on it on eBay, and all the issues remained. Gave up on the 64GB iPhone, and am now back to 6s 32GB with no music. My Dell came with POS Windows 10. I reloaded all of my CDs back onto the computer using Windows Media Player, and copied this to an SD card. WMP goes out on the net and searches for Art, by default. This solved a lot of my Art display issues. This may be the reason that I have not noticed Songs being in alphabetical order on a CD (WMP vs iTunes in a Uconnect environment). Uconnect broke ties with Gracenote in 2011, so no Art will display on a CD that came out after 2011. Uconnect told me that Art must be a jpeg in order to display. In iTunes, I can scan a CD Cover, save it as a jpeg and use it for the Art, and it will display on the screen. I haven't been able to figure out how to do this with WMP, because it goes out on the net. I still have Art not displaying on some older CDs. When I get some time, I'll figure this out. I've only been working on this for 2 years now, so what's a little more time? I hope that the new radios with Apple Play will be compatible with our DJs.
