Jews Under Islam

I have recorded myself singing this poem in the link below.
The melody is the one used in the tradition of the Western Sephardi Jews.
I find this melody somewhat haunting,
which matches the emotions behind the words of the poem.
You might find it interesting to compare...
Below is a link to the same poem sung by Shimon Sibony,
who originates from Morocco and who is sometimes called the 'Jewish Pavarotti'.
He sings Et Sha'are Ratzon according to the traditional Moroccan tune,
which is much sweeter, and perhaps even more pleasant to listen to.
However, some may say that the pleasant melody isn't fully congruent
with the painful contents of the poem.
