iPad, iPhone: Song ratings displayed in playlists and library!

I can’t understand that still no app has not implemented this. Song ratings are
important hints when finding good songs outside prepared playlists.

It should be displayed similar way as in Mac iTunes/Djay library.

Yes this would be a good idea.

I think one of the problems is that an extra rating column would take additional space in the small display of an ipad or iphone.

I would recommand using the title field and adding the rating as (grey) stars in the background (alligning them to the right) For me that would really help selecting the right tracks.
