To transfer online music onto a CD, first legally download the music files, and then use a blank CD-R, CD writer drive and CD authoring software to complete the process. Ensure the blank CD-R functions as a music CD instead of a data CD within the CD authoring software to prevent readability issues with certain CD drives. Computer DVD and Blu-ray drives can almost always function as CD burners as well.
Upon downloading the music files, insert a blank CD-R into the computer's CD burner drive. Open the CD authoring software, and click the appropriate option to initialize the burning process. Select the desired folder containing the music files, and begin burning. If a miscellaneous dialogue window appears asking to confirm the destination drive, select the drive that is the CD burner. Other options may also appear, such as Write Speed and Label. Leave the default write speed, and create a label of your choice for the finished music CD.
Windows operating systems often have built-in CD authoring software, as do many iterations of Mac and Linux. Nero and Roxio are popular third-party solutions to those without pre-installed CD authoring software. Before downloading any music, ensure the files are free from Digital Rights Management software. DRM software may limit or even deny the ability to burn music files. Amazon MP3 files do not contain DRM, and most iTunes music files do not as well.
