How it will work
Streaming, video, sales and airplay represent different forms of music activity. Eligible data will be validated, screened and converted into weighted equivalent units before rankings are determined.
Independence and trust
Every eligible artist independent, signed to Ospo Music or signed elsewhere will compete under the same methodology. Ospo Music executives will not decide rankings, and commercial interests will not rewrite the result.
East Africa
East African music deserves consistent, transparent and globally understandable measurement. Launch territories will be confirmed only when verified data coverage is strong enough.
