Download only legally obtained music onto your Samsung MP3 player. Music is only obtained legally if you paid for it or it was offered for free directly from an artist or studio. That includes music downloaded from a digital copy of a purchased CD, music purchased from an online retailer such as Amazon or Rhapsody or music offered directly through an artist's website or other media outlet with the studio's permission.
Search for free music promotions directly through artist and media websites, but remember to avoid sites that promise more than a song or two for free. While an artist might release a song for promotional purposes for free, a site that offers an entire library of music without paying is committing music piracy and could pollute your Samsung MP3 player with pirated music.
Keep your music collection to yourself. When uploading music to your Samsung MP3 player, you'll likely use the Samsung Multimedia Manager. It would be simple for a friend to plug his Samsung MP3 player into your computer and upload your music collection, but that would be sharing music in an illegal and unlawful way. Make it a policy to keep your music collection private and avoid sharing.

If you have s Samsung smartphone or tablet computer to use for listening to music, utilize Android marketplace to find apps such as Pandora, I Heart Music and Spotify to listen to music without needing to download songs. You will need an Internet connection, but otherwise the music is free of charge and completely legal.
