Good playlists, good hit rate for follows etc. However this is not enough bang for buck for an independent artist that doesn’t have a lot of budget.

Playlist Push is very useful for artists to get accurate reviews. And also makes their songs better known to everyone.

It’s a good promo pool, many people add your songs if is a quality song, if they don’t they still give you a review so you can take the advice and make something better next time!
