Hi I was wondering how do you add a release date of when the song came out using Mp3Tag. Is there a easy way to do this cause I want the song to show its release date when the songs in your iPhone or iTouch instead of just the year , artist name and album. Cause I'm OCD when it comes to my iTunes library and iPhone music library being exact. I have iTunes purchased songs and they show the released date and all that but I want my non purchased iTunes songs to have one so my collection is organized. Can anyone help me with this? Thank you for your time in reading this.

Note: This field will only show up in iTunes with M4A and NOT with MP3
Thank you! I appreciate you helping me out a lot!!
