Exactly. The whole issue is the inconsistency with todays app-centric views of data (iTunes) and the fact that the path hierachy based view of the files will probably still be around for many years to come. I think the best solution would be for the OS/filesystem to provide a queryable layer on top which contains metadata and guarantees consistency without forcing the applications to lock in their data. I can't see how it would be very controversial, as it actually removes nothing, only adds.
