SecondLineThemes

This free plugin helps to easily include 90+ custom and Podcast-specific Subscribe/Follow Buttons anywhere within your site directly via the editor or with a simple shortcode. 
The plugin supports all the major platforms like <a href="https://spotify.com" rel="nofollow ugc">Spotify</a>, Apple Podcasts, Castbox, YouTube, TuneIn, <a href="https://beamly.com" rel="nofollow ugc">Beamly</a> and dozens of others. 
The Podcast Subscribe Buttons are intended for podcasters and therefore the list of companies/icons only include podcast-related companies. (Need a new icon? Let us know!)
With the Podcast Subscribe Buttons plugin, you could display links to subscribe to your podcast across various external podcast platforms, those links may include regular links to your pages on external podcast platforms, direct links to RSS feeds, or URI links to open directly in an external application.
There are a few ways to add subscribe buttons with the plugin. 
First, you can use the custom block in any page/post that uses the new (“Gutenberg”) WordPress editor. 
Also, you can create new “Subscribe Button” sets via the menu that appears in your WordPress dashboard (under “Tools -> Podcast Subscribe Buttons”). Simply adjust the default display settings, add links, and display the button via a shortcode anywhere within your site. See example below: 
 [podcast_subscribe id=”1789″]
Lastly, you can add the buttons directly via your theme or via a custom Elementor widget in case you use one of our <a href="https://secondlinethemes.com/themes" rel="nofollow ugc">Podcast Themes</a>

Now with Gutenberg block!
Sp*tify Play Button lets you easily add a Spotify Play Button for instant play of album, playlist or song by adding the Sp*tify Play Button for WordPress block or adding a shortcode:
Album example: 
 [spotifyplaybutton play=”https://open.spotify.com/album/5PvkD4XryLL9oC4NFItYIM?si=pT6des85S6WPQY7O9ipGPw”] 
Also works with old Spotify URI: 
 [spotify:album:7JggdVIipgSShK1uk7N1hP]
Playlist example: 
 [spotifyplaybutton play=”https://open.spotify.com/playlist/37i9dQZF1E39g1r00WoOvS?si=e05ab8be00c24b39″] 
Also works with old Spotify URI: 
 [spotify:user:jonk:playlist:65ujzBs6WTdWDIr17dOXUm]
Song example: 
 [spotifyplaybutton play=”https://open.spotify.com/track/6te1QldCR1BWiNgwZADpu4?si=ee0dfebaa2944756″] 
Also works with old Spotify URI: 
 [spotify:track:2qntSA2cwerjTduHPuKnW5]
You don’t have to remember these shortcodes. If you are using Gutenberg, there is a block with all the settings you need. And if you’re using the Classic editor there’s a Sp*tify Play Button in the editor.
Simply right click on album, playlist or song in Spotify and click “Share” and then click “URI”. Either paste that together with the shortcode above or just use the admin button and paste the URI there.
You can set the style for your Sp*tify Play Buttons on the “Sp*tify Play Button Settings” page under the “Settings” menu (http://YOURBLOG/wp-admin/options-general.php?page=spotifyplaybutton_settings).
You can also add attributes to customize a single Sp*tify Play Button:
<ol>
<li>
view
</li>
<li>
size
</li>
<li>
sizetype
</li>
<li>
link
</li>
</ol>
All of these will override the settings in “Sp*tify Play Button Settings” for the Sp*tify Play Button and they are all optional.
Example: <code>[spotifyplaybutton play="https://open.spotify.com/playlist/2Xm7KEL5NFHwPboQY22BcZ?si=c99d69e2c916447b" size="0" sizetype="big"]</code>
