Select all the songs (Ctrl + A), right-click, and choose "Send to" > "Compressed (zipped) folder."
Purchase individual songs or albums from a store that sells DRM-free MP3s. (Note: Most modern stores use DRM – Digital Rights Management – meaning the files are locked to that app). Currently, Amazon MP3 (for some older tracks) is an option.
Instead of hunting for risky zip files on obscure forums, spend the cost of a cup of coffee on a Gaana+ or Spotify Premium subscription. You get unlimited zip-file-like downloads (via offline playlists), zero viruses, and the satisfaction of supporting the artists who create the music you love.
For the nostalgic user who truly needs a physical MP3 folder: buy the tracks, rip your old CDs, or use a legal download store. Then, compress that folder into a zip file yourself. It takes five minutes and ensures your Tamil music collection remains safe, legal, and high-quality for decades to come.
Download the purchased MP3 files to your "Downloads" folder on your PC.
