What are refernce tracks? Here's a good answer.
Remember: If you're listening to a track on the web or from a streaming service, chances are you are hearing a compressed fomat that might be processed even further by the source site. Still, the track should still be usable to get an idea of what you can aim for in your mix.
If you come across a good source of reference tracks or have a specific recording you think is good for referencing, send the link to JM
