Broadband music

[Mr D]

VERY off topic (promise I'll start something on-topic soon!!) but I'm at Bony Fella's house, and while I have the PC to myself, I'm abusing his broadband/CD writer (we can't get broadband). What music should I get? My mind has gone blank. I like most kinds, from old style RnB to 70s metal to modern metal to country. Everything gets a chance.
What bands should I give a try? What do you like that you think everyone should listen to? And can anyone name songs that you hear and go 'Oh yeah... I know this one!'?
