Bandcamp, MP3.com and SoundCloud are three of the most popular sites that offer free songs. Whereas not all songs on these websites can be freely downloaded, it is easy to find many thousands of songs that are indeed available free of charge.
Bandcamp is one of the largest music websites where bands can choose to offer their songs for free download. This often takes the form of a 'name your price' option, where donations for a download are voluntary and the songs can be downloaded just by providing an e-mail address. MP3.com has a section on its main page called 'free downloads' that offers free songs. SoundCloud also offers a nearly endless resource of free songs with 12 hours of music uploaded every minute, although they are often offered for free download only for a limited period.
