Outlander Theme

I have been watching Outlander.  I cannot figure out whether I like the series or whether I am just so in love with this song.

Sing me a song of a lass that is gone
Say, could that lass be I?
Merry of soul, she sailed on a day
Over the sea to Skye

Billow and breeze, islands and seas
Mountains of rain and sun 
All that was good, all that was fair
All that was me is gone

Sing me a song of a lass that is gone
Say, could that lass be I?
Merry of soul, she sailed on a day
Over the sea to Skye
