Here are some options:
Free Streaming Platforms: Many music streaming services offer free tiers supported by ads. While you may not be able to download music for offline listening with these free accounts, you can still listen to a wide range of songs legally. Examples include Spotify (with ads), Pandora, and YouTube Music (with ads).
Free Music Websites: There are websites that provide free and legal music downloads, typically from independent artists or labels who have chosen to distribute their music freely. Examples include Free Music Archive (FMA), Jamendo, and NoiseTrade.
Artist Websites and Social Media: Some artists offer free downloads of their music on their official websites or social media profiles as a way to promote their work. Keep an eye on your favorite artists' websites or social media accounts for any free music offerings.
Internet Archives: The Internet Archive's Audio Archive section contains a vast collection of music recordings, live performances, and other audio files that are free to download and use. You can explore different genres and eras to find music you like.
Creative Commons Licenses: Some websites offer music that is licensed under Creative Commons, which allows artists to share their work with certain usage rights. You can search for music with Creative Commons licenses on platforms like SoundCloud or search engines like ccMixter.
Remember to always verify the legality of the sources from which you're downloading music.
