Crossfade is basically fading one song out and fading in another.

So you just have to modify the original audio playing to the user to fade in first couple of seconds and fade out last couple of seconds.

This can be done with some audio manipulation library, maybe something like howler.js or tone.js.

I've tried with howler and I tried with audioContext both has problems

I've did a pretty good script for audioContext but it seems very glitchy

Like progress bar is going 4:00/3:01

Songs are playing multiple after some time
