There's too many. My favourites change depending on the mood but some of the ones which always move me are

"Like waves the sheep rolled in as they drove us from the glenside". The dark Loch- Alistair Hulett

"Ah but ye're no the first that thon Scots have beguiled..".
Flooer O Northumberland- Trad.

But the sparkle of her laughter ever after I'll recall,
Like the linklin, trinklin jinklin as the mountain burns fall"
Bonnie Lass O the Morning- Jack Foley

"you must rise up with the dawn and trudge to the mill in the early morn"
Handweaver and Factory Maid- Trad

Ask me tomorrow and it'd probably be slightly different.
