Como criar um player de música usando HTML, CSS e JavaScript

Olá amigos, hoje neste blog você aprenderá a criar um reprodutor de música personalizado em JavaScript. Usaremos HTML CSS e JavaScript puro para criar este incrível reprodutor de música.

Este projeto [Music Player de Música em JavaScript] tem vários recursos, como você pode repetir, repetir ou embaralhar uma música, reproduzir/pausar uma música ou reproduzir a música seguinte ou anterior. Você pode visualizar sua lista de músicas e também saber qual música está tocando no momento e também pode selecionar a música da lista para tocar. Também criei um vídeo deste reprodutor de música, você pode assistir a uma demonstração ou a um vídeo de codificação completo.
