Playlist Push is the only playlisting service I'd use - I did a lot of research on how to avoid bots and they are super in depth with vetting their playlists - more so than any other platform I found. I don't trust submithub and don't use it because they don't really vet for bots so I wouldn't risk it. So I recently tried playlist push for a small campaign (ya girl is an indie artist ballin on a budget teheh) but it was great bang for the buck.

I found the playlist curators, by and large, to be extremely polite and courteous with their feedback. Whether or not they placed my song, nearly all curators went out of their way to compliment specific parts or performances. Conversely, criticisms were nearly all constructive and specific. (i.e. "vocals a bit low in the mix", "bass is a bit loud", etc.) In the age of internet communication and media marketing, it is very rare to have so many positive interactions via the same avenue or website. Very impressive on that front. Additionally, one curator placed my song on a playlist which instantly quadrupled my listenership. Her review of my material was one of the most touching and meaningful I've ever received. My only sticking point is the price. I find the expense to be a bit high for playlist placements. That said, the playlists themselves are generally quite well attended, and legit. Overall, I would recommend this service to artists (who have enough cash on hand to invest.)

Playlist Push is the best service I've found to help my music get some authentic Spotify streams, and they also have phenomenal customer service! They are my main recommendation of you are looking to expand your reach on Spotify.
