Despite creating a rule in PiL not to repeat the same track within 2 hours there are still hours where it selects the same title by a different artist.
Example: "Christmas (Baby Please Come Home)" has several different versions yet despite every track being labelled the same on the database, I still have the same issue.
Same goes for "Happy Xmas (War Is Over)".
Is there another way to prevent this?
It is not possible to separate tracks by title. You could argue the other way - e.g. "Power of Love" by Huey Lewis and the News is an entirely different song from "Power of Love" by Frankie Goes to Hollywood.
My best suggestion here is that you use the Related Artists feature to relate the artists of "Christmas (Baby Please Come Home)" so they are treated essentially as the same artist and separated appropriately.
Thanks for the answer.. Hope it will be in a update in the future ;-)
