This is one of my favorite pieces, breathtakingly beautiful, by Cristóbal de Morales and performed by the Hilliard Ensemble. Two versions are featured.
Some folks REALLY (viscerally, brutally, completely) object to the sax part, but there's something about it, especially in where it pulls out, and diminishes, that makes it more than the vocals alone (which, in my opinion, cannot be improved upon). (Also, it's important to make your judgement based on analog or high sample rate digital recordings...medium-fi mp3 doesn't cut it).
My hunch is that a careful remix, modulating the volume, approach and decay of the sax portion would make it ... perfect.
A very big word.
Parce mihi, Domine, nihil enim sunt dies mei.
Quid est homo, quia magnificas eum?
Aut quid apponis erga eum cor tuum?
Visitas eum diluculo et subito probas illum.
Usquequo non parcis mihi, nec dimittis me, ut glutiam salivam meam?
Peccavi, quid faciam tibi, o custos hominum?
Quare posuisti me contrarium tibi, et factus sum mihimetispsi gravis?
Cur non tollis peccatum meum, et quare non aufers iniquitatem meam?
Ecce, nunc in pulvere dormiam, et si mane me quaesieris, non subsistam.
Spare me, Lord, for my days are as nothing.
What is Man, that you should make so much of us?
Or why should you set your heart upon us?
You visit us at dawn,
and put us to the test at any moment.
Will you not spare me and let me be,
while I swallow my saliva?
If I have sinned, how have I hurt you,
O guardian of mankind?
Why have you set me up as your target,
so that I am now a burden to myself?
Why do you not forgive my sin
and why do you not take away my guilt?
Behold, I shall now lie down in the dust:
if you come looking for me I shall have ceased to exist.
