Hi Andy,
Yes, I understand the subject of the thread.
All of my music is a combination of live instruments and realtracks.
In addition to the money I have made from downloads and streams, I have also received money from CDBaby for "SYNC LICENSING ROYALTIES" which AFAIK is from music I have done being used on a youtube video that has received enough plays to qualify. $6.34 to be exact, I just checked my account over there
EDIT: Ok, just found a description of Sync Licensing Royalties over on CDBaby:
"Sync Licensing Royalties refers to the use of music in movies, television shows, advertisements, video games, presentations, YouTube videos"
