Hello, I will be dropping 10 hot Spotify and Apple music playlists you can pitch your songs for free.
These are organic playlists to pitch your songs to reach thousands of music lovers. Note: they only accept good music
I will also be giving tips on how to have a successful submission.
What playlists curators are looking forward to

Please have these in mind when submitting your song
Music quality. Keep it professional! ✅
Listen to 5 latest tracks of a playlist you fit to, would your music come next? If you are 100% sure, then submit your tracks. Please also make sure your tracks are:

Free of technical issues and are in a professional standard level of:
Songwriting
Arrangement
Lyrics
Instrument playing skills
Singing technique
Production: Recording, Mixing & Mastering, Sound Design
Artworks
Track and album name
Ready for the public listener
Accepted genres. No growling metal!
Curators accept only afrobeats genres


Extra information? Number of your followers? Not needed!
If they love a track, they will add it anyways.

When providing extra information, please be who you are and present your music as a form of art and not as you are in a business meeting. Feel free to be as lovely and natural as you are with your fans and friends. Bio, press-kit, an impressive pitch, etc. are not needed. Also, you don’t need to provide information about:

The number of your followers on different social media channels
Which magazines or influential persons have talked about your music or have supported it
Which musician, audio/mix/mastering engineer, prestigious studio and so on have cooperated in making the music
How many streams your music already have or how fast you have been growing in the number of followers or streams recently
All these doesn’t really matter. Focus on the musical side instead.

Payola or other types of transactions
Money is not accepted for adding a track to a playlist or mixtape. They try to keep a pure editorial mentality and rather to consider quality, the vibes and be honest to my own taste when choosing a track
Posting physical items, liking, following, sharing, retweeting, posting about the playlists or mixtapes, subscribing, etc. doesn’t guarantee that your track will be added
Posted items can’t be returned
Answering emails and messages
Due to the high number of submissions, They appreciate your understanding if it takes longer to come back to you or not at all. Please don’t take it as disrespect. It’s practically impossible for them to answer all emails and messages. Also, no need to send quadruple emails, it won’t really change anything..

I'll appreciate this knowledge. Thanks

There is now a playlists and curators directory app called Pitchster which makes playlist pitching easier. It has over 10,000 playlists and curators direct contact details to submit songs.

I used musconv. It's a great tool.
