not perfect... would like to press play automatically

Answer 2

Jax maybe that slow prevents u from hearing two songs simultaneously.

Answer 3

Because you set the song url at line 73
const track = new Audio(songs[id].url) once only when creating the app.
you need to use {{songs[id].url}} as attribute of Controls component to make it updated;
alternatively, try updating track in prev() and next()
here is a fix for your reference, in case you couldn't work out.

also, the prev and next button can't call setPlaying which belongs to Control, perhaps disable them if not paused.

Answer 4

Maybe

Answer 5

hmmm, that's strange.
the play button and the prev next buttons all look normal on my device.
before playing the song, i can use next button to change song, and then the src is changed, so then pressing play button will play the newly chosen song.
my edition are at my line 75 79 80 84 85.
you can add track.play() after src change.
