Illegalness Question

This doesn't concern Transformers, but if anyone can clarify this for me, I would be very grateful. I know it does seem out of place, but I don't know where to ask
1-Is it illegal to use Windows Sound Recorder and record music off the internet if it is nearly impossible to find and download?
2-I make stopmotion movies and put em on youtube.com, and I get ALL my background music and voices through sound recording these off other sources of the internet, such as a video playing.
In summary: Is it illegal to sound record music?
AND is it illegal to use this sound recorded music in a movie that I will post on youtube and give credit to?
Example of Credit:What I've Done, by Linkin Park
Any help is much appreciated.
PS-Should I post this in the General Discussion forum instead?
