ITunes Artist Name Doesn't Transfer To iPhone

Question

Hey everyone. I'm using an iPhone 5S, newest firmware, iTunes totally up to date on Mac. I had an issue where I had to delete all my songs on my phone, and put everything back on. After doing that, I noticed that a lot of songs I have aren't keeping the name of the artist that I've given the song, but instead reverting back to what iTunes store gives it. For Example, I buy a lot of video game soundtracks from iTunes. I rename all of the artists names to "Video Games" so they'll be sorted all together so they can all be easily found. So the composer for the Assassin's Creed soundtrack is Jesper Kid, but I change it to "Video Games". Prior to this incident all of them were listed as Video Games as the artist in iTunes and on my phone library. They have all now reverted back to Jesper Kid as the artist in my phone. However, in iTunes under the artist column, they are all still listed as video games, but when I move them to the phone, they don't stay Video Games and turn back into Jesper Kid. In the sorta options for every song, it's all listed to sort as "Video Games", Jesper Kid isn't listed anywhere in the sorting. Does anyone know why it's doing this? Are there any settings that I would need to change where the internet might change it back? If anyone knows anything please let me know, this is quite annoying and I've been doing it like this for years and I've never had this problem. Thanks a lot.

Answer 1

also I should note that other songs not done by Jesper Kid originally, now say Jesper Kid also. So everything that should say "Video Games" as the artist, now all say Jesper Kid, even though in iTunes they still say "Video Games" as the artist.
