gettong free promotional items to give away on your site

[foo55]

in the past i have heard of people doing this, but ive never really thought about it doing it until now.

but i was wondering if anyone knew the correct way about going around doing this? do you contact every company/record label/group that you can think of? or is there something more methodical to it?

any help would be great.
sorry if i posted in the wrong forum.
