Does Enya have a greatest hits album?

You can even choose which collection to buy:

Enya -A Box Of Dreams (3CD)
Paint The Sky With Stars -the besf of Enya (1CD)
Enya-Only Time The Collection (4CD)

All these are highly recommended if you are a serious Enya fan!

I believe she has a box set called Enya the Box Collection or something like that
