If you don't have cover art for every album in your music collection, you can download artwork from free websites. However, if you need to update a lot of music in your library, this method can be cumbersome. Software media players such as iTunes (now Music) and Windows Media Player can help you find album art without having to go to album art websites and manually download the artwork. However, even these can be slow or inaccurate.

One way to speed up this task is to use a special album art downloader. These tools search album art sources from all over the internet, so there is a greater chance of finding the right artwork.

Album Art Downloader is a free, regularly updated open source tool considered by many as the go-to tool for downloading album art.

It uses an impressive range of sources to find album covers and can make all the difference in finding the right cover art, especially for rare albums.
