It looks like you might be looking for a song related to Lord Krishna's flute (Bansuri), and the name Rupa might refer to a few possibilities in this context.

Based on the search results, the most likely connection involves Rupa Goswami, a significant spiritual figure, whose work "Sri Padyavali" contains verses describing the mesmerizing effect of Krishna's flute music on the Gopis (cowherd girls).

There are also references to musical releases associated with the name Sona Rupa or featuring artists named Rakesh Chaurasia (a flutist) and Hemant Mattani (producer/composer) that focus on Krishna's flute music.

To give you the best answer, could you clarify which "Rupa" you are referring to?

* Rupa Goswami (The classical devotional poet)?

* A singer or composer named Rupa?

* A specific music label or series like Sona Rupa?

Would you like me to search specifically for songs by a singer named Rupa about Krishna's flute?
