LOVE Loreena McKennitt. Have all her songs. Her voice is astoundingly beautiful, many of her songs send a shiver through me.
As for Abba, I have to confess that I do like a lot of their songs. Sure, most are pretty shallow, but they have incredibly catchy beats and melodies. On that note, I've always thought their song, "Angel Eyes", was actually about a psychopathic man, with all the talk of being "hypnotised" and "wearing a disguise" and "paying the price":
Last night I was taking a walk along the river
And I saw him together with a young girl
And the look that he gave her made me shiver
'Cause he always used to look at me that way
Then I thought maybe I should walk right up to her and say
Ah-ha-ha, it's a game he likes to play
Look into his angel eyes
One look and you're hypnotized
He'll take your heart and you must pay the price
Look into his angel eyes
You'll think you're in paradise
And one day you'll find out he wears a disguise
Don't look too deep into those angel eyes
Though some Abba songs are really quite poignant, such as "Fernando", "The Winner Takes It All", and "Slipping Through My Fingers".
