I am looking for an app that provides functionality for either directly or indirectly tagging songs as I play them on my iOS device. Currently, I believe that the only direct editing of song metadata is available through the "star rating" system contained in Music.app. It may be that Apple has not published APIs for such content, but I wonder if anyone has come up with a workaround -- e.g., a tagging system that can be exported to text and then imported into itunes?
If the answer is that I need to abandon itunes in order to get this functionality, that's fine too.
In sum:
- on-the-fly song tagging
- ideally, including ability to pre-define tags and apply by button, etc. rather than having to manually edit ID3 tags each time.
