== use of audio files == 

 Dear Mr. Bastique, 
 I'd like to download some audio files and put them in a powerpoint for a presentation I will be giving to college students in Taiwan who are learning about Western culture and music as part of an English summer camp.  Can I have permission to download these files?  For example, I'd like to download Vivaldi's Four Seasons Spring movement - Allegro and Bach's Toccata in Fugue.  Also, I need to download a sample of jazz, blues, country, rap, ragtime, swing, rock and roll,bluegrass, Hawaiian, and gospel.  I am sure I can find these in wikipedia, but I don't think I can download any of them. 
 Thank you. 
 Vicky
