Call me the Pandora curmudgeon but here are some peeves from using this site:
1. The native language of Ireland is "Irish". It's part of the same language family as what they speak in Scotland, but it is not the same language. The native language of Scotland is "Gaelic." There is no such thing as "Irish Gaelic." (http://www.omniglot.com/writing/irish.htm)
2. No matter how badly you want it to be, Karl Jenkin's song "Adiemus" was not used on James Cameron's "Avatar".
3. There is no such thing as a "guilty pleasure"- own your taste because anything else is a way to put on airs.
4. Before you get bent out of shape because Pandora is crediting the artist doing a cover of a song you just know was written by someone else, we all know someone else did it. Pandora is crediting the artist whose version they're playing.
Now, take a deep breath and enjoy the music.
