There's no hard rule, but here's the approach we recommend: treat every new song as a fresh marketing opportunity, and space your releases out by about a month.
Why a steady cadence beats batching
Each release is a reason to reach out again: to curators, to playlists, to your fans, to the algorithm. A new single gives you something fresh to pitch and a new excuse to show up in people's feeds. Drip-feeding releases keeps you visible far more consistently than dropping everything at once and going quiet.
It also compounds. Every promotion push (submissions, Meta ads, social posts) lifts not just the new song but your whole profile: monthly listeners, follower count, and the odds that Spotify's algorithm starts working in your favor.
Why about a month between songs
Spacing matters because of curator fatigue. If you fire off three new songs in two weeks, you'll be hitting a lot of the same curators in quick succession. Someone who just approved your last track is less likely to say yes to another one right away, even if they liked it; they want variety on their playlist, not the same artist back-to-back.
Give it roughly a month and that resets. The curator has had time, your last song has had its run, and your pitch lands fresh instead of feeling repetitive.
A simple rhythm
This is the same logic a lot of successful independent artists follow: frequent, well-spaced singles rather than one big drop and a long silence.
