I have an artist's name that is just letters. Some albums list the name with periods, some don't. I highlighted all of their songs and changed the name at once without periods so that it would group together. On iTunes, it shows the name without periods. When I put it on my iPod or iPhone, it still shows the name without periods under the device in iTunes. However, the device itself lists one album with periods, so on the device it has that album separated. How can I get it to sync correctly?
