My project in simple mp3 player

[fortunatekidz]

Hi everyone, I am still new in VB, and I have this simple design of mp3 player for my project but I don't know the correct code. I've tried learn it from youtube, but still can not make it work correctly. I have 2 listbox in my mp3 design, the bottom one is for folder seach only ( I use folderBrowserDialog ) and the top right listbox is for playlist which is for mp3 file ( songs name only ). So, once I click Load Album button, it will search for folder then I click the folder, all files in the folder will show up in the bottom listbox and at the same time "songs.mp3" files show up too in the playlist box. But I don't know the correct code for them. Could anyone help me please....thanks alot

This is exactly what I want my mp3 player looks like....( this picture is just a sample )
