Hey guys, I've found a not-bad program, which can help to rip the background music off YouTube videos easily, and don't have to pay! It is Moyea SWF to Video Converter, which is a SWF converter software program to convert Flash to popular videos, like AVI, FLV, MPEG, WMV, MP4, 3GP, etc. However, it does convert Flash to MP3, which is right for the background music! Well, it's not a free program and cost some money, but it does have a trial version which is free! And, you don't have to pay, if you only use its trial version to rip MP3 file from flash file, as the limitation of the trial version cannot effect on audio file!

Thus, you don't have to leave messages in the "comments" "what's the name of the background music?", and then try to buy from iTunes, but get it immediately with SWF to Video Converter.

Then how to rip music off youtube videos with SWF to Video Converter? It is quite easy, as it only a little program, several clicks will make it.

Step 4. Click "Play and Capture" to start the conversion. Later, open your folder to find the MP3 music and enjoy!

Note:Because the SWF file from URL would be greatly influenced by internet speed, it is strongly recommended to click "Play Movie" to fully play the movie once before capturing.
