1) Work Hard Playlist Hard: this small team of curators have a broad range of genres included in their playlists, so they may be a good place to start whatever category your music falls into. You can submit to them via a form on their website.
2) Songpickr claim their playlist interest lies in ‘organic’ and ‘vintage’ sounds, so if that fits the bill with your music, it may be worth emailing them or contacting them through Facebook to see if they like your stuff.
3) Indiemono is perhaps one of the biggest independents, and are interested in a huge range of genres and types of music. Being one of the larger independent curators, they will generally only allow submissions through Submit Hub.
4) Tropikult are another fast-growing independent curator, who accept music submissions via their website, and are looking to expand their following and their playlists.
5) Soundplate are generally associated with electronic and dance music, and they also let you submit music via their website. They run a blog, too, which helps to boost the publicity of their artists and musicians.
6) Like Soundplate, Tune are interested in electronic genres, but also accept indie, alternative, and experimental music, so a real range of options. They can receive submissions via their email, [email protected], and also have a collaborative playlist on Spotify which artists can add to.
7) Cloudkid have an enormous Youtube presence, as well as their influence on Spotify. Another leaning towards electronic dance music, they also accept submissions via Submit Hub, and have a very strong following on Spotify.
