I have a separate Collection named XMas (not "Christmas", also to have it sorted away like you) and use the filter feature to make it invisible. Additionally I often filter away all songs that are not added to any collection.
I like the feature that MSP replaces underscores with blanks when it guesses song titles from filenames. My song files don't contain blanks and follow a naming scheme like "AllOfMe_C_Tx.PDF". MSP replaces the underscores and inserts blanks into "camel casing" so the result is "All Of Me C Tx" - perfect for my usecase - please don't change that.
