This market will resolve to the most searched query in Google in 2025 in "MUSICIANS" category.

The resolution source will be Google's annual "Year in Search" (2024 edition here).

If there is no such report (or no category) in 2025, another source or way to asses the most searched query will be used, according to @itsTomekK and with the help of the community.

PS If there is more than one submitted answer, that almost does not differ in meaning, the earlier one will be used.
