I'm with you re Puccini - goosebumps every time I hear 'O Soave Faniculla' and I was thinking about linking 'Un Bel Di Vedremo' on my previous post. I actually think Turandot is probably his weakest opera despite having his best-known aria in it - a happy ending, what's that all about? For the last few years around Christmas time there's been an excellent performance of Tosca on the telly with Jonas Kaufmann, Bryn Terfel and Angela Gheorghiu in the lead roles. Keep an eye out if you haven't already seen it.
On your other posts, I thought there would be more mention of film music on this thread. As Sylar says the Lord of the Rings Trilogy is terrific. I'd add Ennio Morricone to his list of composers (not necessarily the spaghetti western stuff, although I quite like that too). Also the Godfather main and love themes and Dunbar's theme from Dances With Wolves (done with bagpipes here- https://www.youtube.com/watch?v=dgZxdVJH8fc).
On Wagner, I like his music a lot, but I've never managed to watch one of his operas all the way through - they do seem rather hard work to me.
