Well - I hate metal, I can just about have a laugh with AC/DC and I get on OK with Led Zepplin, anything else is just wrong for me (which makes it hard to find things to play on the electric).
Generally I listen to acoustic guitar type folk (Jansch, Renbourn, Davey Graham) and Nu Folk (Vetiver, Espers that stuff), renaissance and baroque stuff, classical guitar, 60s rock and some of the newer Fat Possum raw blues like RL Burnside, T Model Ford or Seasick Sam.
