STEAL IT FROM THE INTERNET
And then they start selling it as you get bored of it from listening to it on YouTube so much.
Find it on youtube then steal the audio on this site http://www.youtube-mp3.org/
I know! I found this song by P!nk, Boring, and I cant find it ANYWHERE!!!
Wait, people actually buy their music from iTunes?!
File sharing websites are there for a reason, people.
