Why is my other section so large?

Here is a screenshot of my iphone 5 storage. As you can see, the "other" section takes just about 40% of all of my space. Which stinks because I barely have space for anything else. Can anyone tell me why this could be so large? Or what I could to reduce this?

Most of the "other" category is album art from your music. Especially if you have iTunes add the art - as iTunes likes to add the high resolution pictures. If you don't have much album art, then I would suggest restoring your iPhone. Sometimes if you manually add songs (as in not through iTunes) then it will add on to the "other" category.

  • Why is the other section on my iPhone so high Why is the other section on my iPhone taking up 4.77 GB? I only have 16gb so that is a HUGE problem. I already restored it once from backup and it even takes up more after! Please help me. No, It wasn't jailbroken and I restored twice and it didn't work.
  • Why is my music not showing up in the artist section of my iPhone? I just started adding music to my Iphone 5 and quite a bit of the music will not show up in the Artist section. After searching for it I can usually find what I was looking for in either the Album or Song section, but I find it kind of annoying to have to search so hard just for music. Any idea what's causing this?
  • Why does my imported videos go to the picture section on Windows 8? I Uploaded some Videos on my Desktop, whenever i connect my Iphone 4s to the Computer, it takes me to the Pictures section, and my videos end up in the Pictures section, which is a problem because my video editor thinks that I'm trying to upload a picture not a video. I have windows 8!
