I host a New on Spotify page on my website. It lists new releases added to Spotify over the last 7 days, all contained in an easy-to-search database. To use, select your country then search for a genre, or simply browse using the Next Page button.
I love listening to the newest singles, and to that end I curate a weekly play-list of the best single and EP releases of the moment., usually ending up with 100+ tracks. A wide range of genres are represented; the only rule is they have to be good pop songs. I like to think of it as one of the most comprehensive new releases' play-lists you'll find on Spotify.
