Oh I missed these, thanks for bumping.
She does like Neil Young!
She has found Pandora, which really serves the function of this thread beautifully. She has two channels so far -- the Highwaymen channel (Highwaymen: Johnny Cash, Waylon Jennings, Willie Nelson and Kris Kristofferson), and the Iron Man channel (Black Sabbath). Basically, the first is "outlaw country" (her favorites are Johnny Cash and Merle Haggard) and the second is heavy metal (Black Sabbath, Led Zeppelin, AC/DC, etc.) So far the only surprise Pandora has turned up (most of 'em are just songs she already knew and liked) is Guns 'n' Roses, I forget which song though.
She needs to start a Beatles channel next, then she'll be set. (She does like Oasis, too!)
Oh and a pop channel too. She does like some current pop, not much but some. She would not stop singing "Fireflies" for about a month. Ugh.
