The mini-player sat on the home screen of Android smartphones with quick play and skip buttons, as a convenient alternative to opening the full music app.
Some users are calling for the Swedish firm to reinstate the feature, after noticing that it was quietly withdrawn.
Instead, Spotify is informing people to use its playback notification and device lockscreen options.
“We always take retiring features in Spotify very seriously,” Spotify said on its community board.
“We’re pouring our energy into new ways of creating the best experience for our users.”
In response to intensified questions about the decision, a staff moderator posted on Monday, saying: “We’re hearing you regarding the removal of the Android Widget.”
A vote to bring the feature back gained just over 2,000 names, before Spotify explained that it “isn’t something we have any immediate plans to reintroduce”.
“Fixing a problem that doesn’t exist? Seems silly to remove functionality like that,” one Spotify user wrote on Twitter.
“Which genius at @Spotify decided it would be a great idea to remove the widget on Android… well done at removing the most useful feature you had,” another complained.
