Reng Studio
Read full descriptionHide full description
Reng is a home for music that asks something of you. Not a feed built to keep you scrolling. A place where artists publish their work, listeners find things they wouldn't have found otherwise, and the people who made a record are credited by name. WHAT YOU CAN DO Listen — Play full tracks, build playlists, follow the artists you care about, and keep listening while your screen is locked. Discover — Find music by genre and by the people who make it. Every artist here was let in by a person, not an algorithm. Reng it — Record a short sound from where you are. A street, a room, a rehearsal. Add it to the feed with the place it came from. Talk — Comment, reply, and message other listeners and artists directly. Shows — See who's playing near you. FOR ARTISTS Upload your work in the format you have, including lossless. Credit everyone who worked on it — composer, arranger, player, engineer. Your music and your audience stay yours. Reng supports Persian and English throughout, right-to-left and left-to-right.
