I discovered the My Music feature yesterday and while I think the implementation of it is flawed the idea of it is fantastic. I have a USB stick with 15 folders on it basically setup by Genre.. you can select a folder and then shuffle the songs from inside the folder easily and you can also just shuffle ALL the songs on the USB stick quickly, I love that.. Using my voice I can get to the My Music section also, the issue I have and others have stated the same is that you have to copy songs to the My Music section one at a time from your USB stick, that is silly. Still, I will spend the time to get a fair number of songs on there, you know, just because I can.. Love the idea of having a selection of my music available with out having to plug in a usb stick or even being able to play my music while my phone is plugged in for Android Auto use. I have my files tagges nicely with album art and so far all 32 songs I have transferred over have had zero issue displaying the art or track and title info. Gonna call it a win for now, there appears to be around 6GBs of space, which should translate to close to 750 - 1000 songs if my math is correct.. that is plenty to choose from..
