Although not an Audya owner at this time, I agree with Bernie. A Music Finder helps trigger that memory and aids in songs I might want to play.

On the other hand having Registrations setup for some popular songs out of the box is helpful too if they have some naming which indicates what it might have setups for. We know it's difficult to use actual song titles out of the box due to copyright laws, but in many cases users have spent time on the other boards and made those changes available.

Either way would be fine if I were an owner but I would point more towards the Registration aspect since it can have deeper settings and can be modified to the player's liking.
