You can download the Spotify app for Mac, Pc or mobile and you'll then have access to anything you need samplewise... its great for music discovery, type in someone you like and use the related artists tab over and over until you've gotten to something sick that almost nobody has heard before haha. Once you find something you want to sample you can do it many different ways. Personally I reroute audio output right back into my computer's input. It's easy, I use a headphone splitter to plug into the headphone jack so I can monitor what I'm doing, then just route a cable right back into the input jack. now the computer thinks its external audio being recorded, u can get anything off of the web, other applications, etc. Any audio whatsoever, its the perfect way to get something rare and obscure to work with. Or use the Soundflower app (Mac) to internally route audio from app to app. And there you go, the world is now yours.
