youtube changed alot of that..or shall I say the internet changed that..people pay good money for rare records so they can possess a one of a kind item,something that no one has on vinyl,cd,mp3,etc....now thanks to the internet,people can share their taste with other collectors online like youtube,podcast,internet radio,etc..only bad part is that people can rip the songs for their mp3 collections..and yes even from the sitting in the park show unfortunately
