  • Why isn't iTunes letting me download this song to my song app on my iPhone? I just purchased a song but it's not showing up in my music app and when I go to where it says purchased in the iTunes app I hit the cloud but it won't download to my music app. Is it because of my storage? What do I do?

  • Why does my Pioneer car deck skip? I have a DEH-X6500BT. When I use it for Pandora, it doesn't skip, but when I plug my iPhone into it (or use the bluetooth connectivity) it will start playing a song for a while (usually around a minute and thirty seconds), and then I hear a whoosh, the song gets muffled, and it skips to the next song. What's up with this?
