If you’re using the Blubrry Audio Player then yes, definitely. Any plays that occur thru the player will be tracked in your Blubrry download stats.
If it’s a third-party player, and you’re using Blubrry Media Hosting, and the player is using a Blubrry media file link, then those plays will also be tracked.
If it’s a third-party player and you’re using Blubrry stats with someone else’s media hosting, then the Blubrry stats redirect URL must be present within the media file URL being used by the player in order for Blubrry to track your downloads.
