I listen to my rock at home on the compu these days...I've got a decent pair of speakers (JUSTer) and a cool "SuperBass sytem" so I'm happy with my set-up though it's 4 yrs old now.
Until, I get a smaller fuel-efficient car, I'm listening to the AM radio in my '77 Pontiac still, but luckily, AM radio still hosts some good "oldies" stations.
