I did take Icelandic courses when I was living in Finland, but that was quite a while ago (and the obligated Old Norse courses were even longer ago), so I can’t say it’s still fresh in my mind.
One of the things that has always fascinated me about Icelandic was the pronunciation, especially the fact that they pronounce t’s in words that don’t have a t in them, for example in Íslensku my teacher pronounced a t between the s and l.
By now I don’t remember much more than:
Góðan daginn, ég heiti Mirjam.
Hvað heitir þú?
Of the song I understand bits and pieces.
Þetta er það lengsta sem ég fer = This is the furthest I will go
Aldrei aftur samur maður er.= = (I) will never be the same man again
Ef ég vinn í þetta eina sinn = If I win (or: work) this one time
er það samt dauði minn = it will be my death either way
Áfram ríð, hjartað pumpar tárum = While I move forward, my heart is pumping tears
Dag sem nótt ég geng nú einn = Day as well as night I’m walking alone
