I liked "Within Temptation" a lot and "Sisters Of Mercy" and "Dire Straits", but only if I'm working. For relaxation I'm more in to New Age. I have loads of cd's with New Age like Spirits Of Nature 1 to 6, Pure Music, Enya, Oliver Shanti & friends, Adiemus, Clannad, Enigma, Massive Attack, Elbosco, Sacred Spirits and so on... Soundtrack of Braveheart, Last Of The Mohicans (Clannad), The Mission (By Ennio Morricone), LOTR etc...
I'm not able to put in a link, but if someone can please do. It's such a calming kind of music and so easy listening.
