How to search songs on google? Its so good idea, You can find any song you want easily.
Another good way of finding MP3s (or other formats) is using Google and typing the following:
parent + directory + mp3 + OR + wma+ #dido#
Replace #dido# by whatever artist you wish to find, for example:
parent + directory + mp3 + OR + wma+ #Lamb#
You should get plenty of dirs with MP3s or WMA files (you could add OGG, etc, to the query). Cheers.
