I got it for 2 things - 1) Power of Celtic - one of the first few tracks I had heard back when I was new to the genre.
2) Spiritual Healing RMX - I love this(read as original) track and all its remixes. As AP used to say, the best is the live unreleased mix. That is amazing.
Now to the CD, I spent good amount of money to get this one recently (sells for 30+) Power of Celtic sounded baaad! Very disappointing, it did give me a solid nostalgia rush. But the track itself was a huge letdown. Rest of them are OK'ish, nothing groundbreaking in there.
Spiritual Healing RMX is the standout for me. If you are also looking to have just this one track, its a smart decision to have it as a part of some other compilation CD or vinyl other than this. But hey, we all make mistakes.
