I need more music

Hi people...

I am from Czech republic and I have BIG problems to get some trip hop music. Of course there is no problem to get the most popular bands like MA, PRTSHD, Tricky... but if I want some more underground bands like Sunday Munich, Mistake theory and 50% of the bands about which U all speak I cannot do anything. Yes I can order them via internet but its extremely expensive. No I dont have problem to spend some money for music but I am only a student and this is not way 4 me. And Kazaa is bad solution because I can get all I want...
How do U all get all this music? Dont say U buy everything. Please help...
