I recently suggested this concept, it seems that the Telegram team did not like it, because the idea was not published in the Telegram Designers channel, but you can always see my work here, so enjoy it, and I hope you like what I do.

🎶 Audio Sync
Listen to your favorite tracks with friends, even if you use different devices. The entire playlist is shared, for uninterrupted listening to songs.
👥 Group Chats
Create shared rooms - from small companies to the entire city. Turn listening into a real stadium effect.
⏱ Perfect Timing
Music sounds synchronously for everyone. No delays - one wave of emotions.
🔇 Easy End
Sync stops when the sender turns off the audio.
