So if I add an album to my iTunes library and every song has the same album title in the info and the same artist, except a few songs have the same artist but feature another artist, instead of grouping the songs in 1 album by the album title, or even by the common artist, it assumes that Artist ft Artist is a whole new artist and is separate from the album I uploaded (even though the songs with Artist and Artist ft Artist have the same album title) and creates a different album for Artist ft Artist with the same album name?
This doesn't seem broken to you? I'm not saying this is new to iOS 7, just surprised that it hasn't been fixed yet, especially given that all stock apps were redesigned.
I'm saying it extends well beyond Apple & iOS. There are numerous music players that handle metadata/Tags the same way as iOS. If people are "complaining" about it making a second/third/etc album because of a featuring artist, why don't you get mad about if you have a space at the end of the artist name or album versus not having one? Doing that will give you the exact same result. It's just how it is.
How is a music player supposed to know where to stop grouping an artist?
