I've always thought Arabic sounded beautiful. English is a very matter-of-fact language, just like German (and they're both Germanic) but you can see their reflection on the more stoic and serious, sometimes cynical and sarcastic, tones of English and German speakers.

The romantic languages all have a fun, bubbly, and colorful bounciness to them.

And then Arabic is just so elegant and, like you said, vivid-sounding. There's also a wisdom and warmth to it. I don't know a lick of it, really, but maybe one day.
