If you’re a classical music buff and want to have classical music saved to your computer or for an MP3 player rather than just streaming it via a service like Pandora, we recommend checking out MakeUseOf.com’s article that lists three services you can look into for downloading classical music for free.
The three websites they highlight are:
Classical.com, where every week “an entire album is available to download for free.”
Wikipedia:Sound/list, “a huge repository of free classical music”, though the file format is .ogg so you might want to convert the files (and be aware that the “conversion will decrease your audio quality”).
Classic Cat, “the Google of classical music. The index of this classical catalog comprises over 5000 free to download pieces.”
