Vince, can you please elaborate more on copyright matters within a song?
And is there any websites that have free music to download and use? Something like 'stock music'... MIDI files are ok too. I tried to google it, but all it can show are those illegal websites for people to download MP3 songs..
They are plenty of stock music, sound effects CDs which the film or creativity industry uses for their work. However, like stock photographs, they are not exactly cheap and it's difficult to sample the music first since most of them are ordered off catalogues.
Alternatively, you can check out the following organisations to enquire on the usage of copyrighted music on your website.
