Top 10 "Must Know" Opera Songs

This is just my selection of the top ten "must-know" opera songs for newcomers to the genre (or lovers of opera who want to listen to a couple of classics). I've tried to be fair and spread the list across Italian, French and German pieces. You will also find arias (solo acts), duets (two person acts) and chorus numbers (featuring the full cast), although you will probably start to see a pattern with certain singers * cough * Pavarotti * cough* . 10.
