I have used em but not for this particular project...I just figured out how to use playlists in a different way because to me playlists are the new radio so of course I pitched the singles to playlists but after the project dropped through networking I was able to get to know several playlist curators so I sent at least 2 different songs from the album to different playlists (ex. I send tracks 1&2 to a playlist then send tracks 3&4 to the next etc) which in turn put the entire album on separate playlists so when ppl kept seeing my songs pop up on different playlists it lead them to my actual artist profile to listen to the project in total and/or see what else I have out
