A WhatsApp bot where you can send names of songs, it will download, convert, and send you an mp3 file. It works by utilizing the Twilio WhatsApp Business API, ytdl-core for downloading, and a custom build of FFmpeg for conversion.
Don't know about other countries but in Pakistan 🇵🇰, We have Social bundles meaning data that can only be used on social networks like Facebook, WhatsApp, etc. These bundles are real cheap, everyone has these and to an extent, they are must-have for University students like me. The idea is to use that data to download songs while I'm on the bus waiting to get home.
