I have been searching for a music player for some time that has the following functionality and cannot find one:

1) Ability to rate a song. 1-5, 1-10, whatever.
2) Ability to create a playlist to shuffle songs that are, say rated 5 or above. Another playlist to play songs rated 8 or above, etc.

I have been searching for years and I have not been able to find a single app that can do this core feature of iTunes.

Anyone know of any? Free or pay.
