Transferring your entire CD collection to an iTunes library can be a time consuming project that you'll want to get right the first time. While iTunes provides some error correction, no validation is produced at the end of the importing process. The XLD software not only can import CDs into many different file types, but it also provides accuracy reports to certify that CD importing went through correctly.
In fact, XLD has some worthwhile features to manage your CD importing experience. First off, the app supports a multitude of file types, including all the usual suspects: AIFF, WAV, MP3 (if you must!), FLAC, and Apple Lossless. Pointing the XLD software at your iTunes media folder ensures that all your music smoothly transfers into your iTunes Library. It can even query a couple different compact disc databases to find your CDs' artwork and track names.
The main feature that sets it apart from iTunes is the option to use AccurateRip reports. Unlike iTunes, at the end of the ripping process a text file is generated indicating if your CD was imported without errors. For example, if the physical CD has some scratches, it may not be read with entire accuracy. Even though iTunes and XLD employ error correction, the report verifies if the CD was truly imported without issue. And to top it off, XLD is kinda free since you are allowed to donate if you enjoy using the software.
Getting your CDs cleanly ripped with all the metadata intact will surely make you a happy camper. How are you backing up your CDs?
