Smule

Smule is a social music app where users sing along to backing tracks, record karaoke-style performances and share them with a community of other users. People use the app both to perform on their own and to collaborate on duets and group recordings with others on the platform, building a social layer around singing rather than solo recording alone.

Based in the United States, the site sits within the music category, built around performance and sharing rather than passive listening, with a catalogue of songs across many genres and languages.
