Dear anheloeterno, this is of course Shania's song but the version that last.fm radio plays is so strange that you can't believe that it would be she singing. I had a feeling that it was so bloodless (no spirit in it)
Sounds a little bit off. Still an amazing song, but I agree with others here, this does not sound like Shania singing this one to me. Though I know this to be one of her songs, this version does not sound like her doing the actual vocals for it.
I just found the 'Solo Radio Edit', which neither has the 1 minute "talk" intro, nor the timpani thing (which I believe was only included in the 'Right Mix' - aka. the 'I.V. Mix' in the first place).
It is, if possible, an even better version, and I shall at once listen to it until I'm sick of it :-)
