I have never used LE so i cant say…but i have never had a problem with my tagging if done properly. This is my method.
Download songs put into Media Monkey, revise tagging and get all the info in properly (Star Rating in Media Monkey does not transfer to Itunes or Traktor)
Then I import my songs into a Playlist ( Playlists i arrange by date…i download the song…not my actual set list)
This is where i will use the Star rating and start building my set, and will create playlists based on Date of my show. Once that is done i will open traktor and import the playlist into my Traktor Playlists.
I also have meta playlists or whatever they are called that will automatically create playlists based on Grouping field or Star field etc.
Example:
The Playlist will automatically add songs that have 3 – 5 star rating, with Electro Genre, and have Big Room, Banging, Peak Hours tagged under the grouping field.
