On the Slane Castle dvd, it quickly becomes obvious that Hayley has a beautiful and powerful voice. This becomes a proven fact when you see the number of cds that she currently has for sale on the internet. Having only seen her on the one dvd, I was unaware of her true singing style until I purchased her "Paradiso" cd. Unlike what I witnessed on the "Greatest Journey Collection," this cd sounds more akin to a collection of melancholy ballads. And while this may not be my preferred music style, I am sure that other people will find it to their liking.
