While the world buzzes about Spotify, Rdio and MOG, one of the coolest things about these services is that it opens a whole new world of promotional opportunities for groups to share what they have been listening to. The biggest door this open is to get features on blogs where these blogs show curated playlists by musicians. The always awesome blog Property of Zack is one of the first into this exciting new format and has been doing awesome Spotify curated playlists. Some of the first they have is where all of the groups on Thrice’s latest tour each contributed a playlist of their current favorite tracks. The ways these playlists can be used are endless, whether it is a playlist of what inspired your latest record, seminal tracks or even just your favorite tracks of a certain genre. This is sure to become one of the more popular features on every big blog in the land. To get on the boat, start pitching some blogs you’d like to see your music on for this feature and see if they will get on board.
