Thanks for the kind words!<p>&gt; If I&#x27;m not wrong, quickly reading your beautiful synthetic python code, you store music in your server (as a MongoDB blob). ins&#x27;t it ?<p>Nope, the bot only stores track title, performer and id. Actual media is stored on Telegram servers.<p>&gt; Just an idea, maybe always interesting for sort of &quot;auto-deleting&quot; sahring, as secret messages (but could be wrong).<p>Yes, I&#x27;m thinking about it.<p>&gt; I noted that search functionality could be developed to understand better what user are looking for, but this is not a criticism of your excellent work, just a feature for a future implementation!<p>Sure, I&#x27;m open for any suggestions and criticism :) I&#x27;m thinking about how to improve it.
