I'm a complete noob with WP of any version and ended up connecting my phone to my Win7 PC with USB cable and was prompted to install WP8 software on the PC. After installing you are given the option of what file types to sync. I just synced music and all music including DRM music was synched to the phone and playable using XBOX music. However, album art isn't working anymore for most of the music as I selected the option somewhere to use online album art and data. I did not have the double album folder issue that some folks have posted.
I tried SkyDrive first but was not able to even play any DRM music placed on SkyDrive using the PC, just non-DRM music could be opened.
I haven't tried synching any music from iTunes yet as that's all on a different PC and nano.
