Everything depends on tone, of course.
I was being facetious about German sounding awful; I hope you understand. It seems like a much more guttural language than, say, the Romance languages. Or English for that matter. It has developed a reputation for sounding 'harsh' as a result.
Frankly I don't put any thought into which languages sound "phonetically appealing". Languages are... what they are. Arguing about which ones "sound prettier" is pointless in my eyes, I couldn't care less.
