Ezra Pound - An Immorality analysis

Ezra Pound's An Immorality has very few papers analysing its themes/meaning. Could someone please give me an idea of what this poem is, it's meaning? A critical analysis of this poem with its symbols and how it relates to Modernism and Imagism that Ezra Pound is famous for having contributed to?

An Immorality – Ezra Pound

Sing we for love and idleness,

Naught else is worth the having.

Though I have been in many a land,

There is naught else in living.

And I would rather have my sweet,

Though rose-leaves die of grieving,

Than do high deeds in Hungary

To pass all men's believing.
