I like my music library looking as professional as possible (as in I make sure to edit everything to make it look like I bought every song on iTunes). However, Apple now does the thing where explicit songs are tagged with an E. Can we have an function?
It has already been supported for a long time. Once you add your file to CopyTrans Manager, right click on it and select "Edit" (or open it with CTRL+E), then from "Media kind" drop down select Audiobook. After updating your device, the audiobook will be visible in the "Books" app.
