New WP user, 8x owner. Just signed up for 30 free trial of music pass. Two questions: (I) music streams over wifi and cellular, but noticed a few "skips" during play over cellular connection- is this common, (ii) you have the option to "download" song-is this the same as purchasing it, because there is also an option to purchase the song for $1.29. Thanks in advance for responses. As an aside, 8X is an A+ phone-no reboots, no heat issues, inductive charging is great and I have experienced very good battery life. The interface with my business mail server etc. is nearly perfect.
