<p>&lsquo;TUNAY&rsquo; marks Zack Tabudlo&rsquo;s first single release of 2026. The &lsquo;Habang Buhay&rsquo; hitmaker had a busy 2025, dropping four tracks throughout the year: &lsquo;Diving,&rsquo; &lsquo;MANLOLOKO,&rsquo; &lsquo;Naguguluhan,&rsquo; and &lsquo;For You.&rsquo;</p>
<p>With four distinct artists coming together on one track, &lsquo;TUNAY&rsquo; is shaping up to be a collaboration worth hitting repeat on!</p>
