Well, this is tough because I have many favorites. I love one band, but I also love another so much, and then another, and yet another, and before you know it, I've already listed most bands I know. lol But I will do what I can to be short and sweet.

Favorite bands: Runrig, The Levellers, Big Country, Great Big Sea, and Muse
Favorite songs: "Running to the Light" and "Big Songs of Hope and Cheer" by Runrig, "Indian Sunset" by Elton John, and "You Oughta Know" by Alanis Morissette
Favorite artists: Loreena McKennitt, Lisa Gerrard, Elton John, Michael Jackson, Alanis Morissette, and Stevie Nicks

Not exactly what I would call concise, but hey, I tried. lol
