If you play music in your business or want to include it in your product you need clearance to do so from the owners of that music. PRS and MCPS represent the owners and can get you the clearances you need. We are a not-for-profit organisation, enabling you access to the world's music in the most efficient way.
If you want to check the repertoire covered by MCPS and/or PRS please visit ISWC's database: http://iswcnet.cisac.org/ISWCNET-MWI/logonPublic.do
