Playlist Push are the best in my opinion There are a lot of low activity playlists but I have got onto enough good ones to make the service work for me.

Easy to use, always helping you if needed, just overall great and will use again!

PlaylistPush is a great tool to promote your release on Spotify. I have used it numerous times now, with two different artists names and it's a great way to boost your single when it has been released. The results of the campaign depend on how good your track is of course and how well it fits with the curator's playlists, but my latest one had amazing results. It's a bit more expensive than competitors tools though, but if you really are convinced you have a good track at hands, it's worth doing a campaign to get the most out of your release and boost the streams and algorithm.
