If you all feel very bored one day, and you want to try out something new just for the fun of it, listen to classical music.
A few of such pieces (operas) are,

Nessun Dorma (Pavarotti) - This rocks damn lots, especially at the chorus, turn on the volume to hear the sound of the string instruments at the beginning http://www.youtube.com/watch?v=VATmgtmR5o4&feature=related

Ave Maria (Pavarotti) - you may have heard this before

Mario Lanza (Toselli's Serenade)

Granada (Pavarotti) - light-hearted music

Caruso (Pavarotti)

Hero (Mariah Carey and Pavarotti) - VERY INTERESTING

Well, if you listen to these pieces and like them, just go search for more pieces!
