If you're willing to copy everything to your phone musicolet can do wonders. It has bulk-tagging, auto-complete from other tags, built-in lyrics support and very good album art picker
In Turkish we have plural version of you called Siz which can be used both adressing multiple people and as formal you. There are no pronunciation differences so it depends on the context.
(e.g. Sizin sınıfınız iyi. uses it as plural, Sizi bir yerden gözüm ısırıyor. uses is as formal you)
