Looks like the Google Play Music error that plagued the G2 after the Kit Kat upgrade has spread into the G3. Been getting the "cannot play the requested music" error all day. Really bummed, had high hopes it wouldn't have followed me!!! :'(
Don't jinx yourself!!Interesting. I have been trying to recreate that, as it drove me nuts on the G2, but I have yet to encounter it on the G3.
