I rarely listen to music when I knit, if I do it's been classical and folk, the Von Trapp Family Singers. (And yes, the REAL Von Trapps, not the Sound of Music soundtrack, although occasionally that is in too.)
If I feel like music when I'm knitting I'll just sing myself, Josh Groban, and Colin Ray, Glen Campbell, John Denver, old stuff before my time.
I'll sometimes watch TV series when I knit, I Love Lucy, Road to Avonlea, The Brady Bunch. Last night, I watched a movie in Spanish, it wasn't dubbed in English, so reading the subtitles and knitting was a little difficult.
