Ive noticed a lot of my songs wont retain there ID3 info correctly, mainly the artist. It seems to be the same certain bunch of songs. Im guessing there not all the same ID3 version? Anyways i noticed iTunes will let me convert all my ID3 tags to the same version, and reverse unicode. So i wanted to ask should i? and if i should what version should i convert them too? and should i reverse unicode them also? And last but not least will whatever version i convert them too, still read on my X5?
