What are the scriptformulas for following tags ?!

Hello there !!

First things first: Sorry for my bad English, i am not a native speaker !!

My “problem”:

I want “Picard” please to tag my huge .mp3-Collections as follows (in this particular order) :

Artistname - Song title - (approx.) date of release AND (important) GENRE !!

Is genre any possible ?

Do not point me to the scriptsite but please show me the plain “formula” because i do not understand those paintings :wink:

Thank you very, very much in advance,
