The path in the error message

Error 277 for "open "A:Chrome DownloadsJhalla_Wallah_(Remix)-(MusicTub.Com).mp3

looks strange. You may have to use something like

path = r"A:\Chrome Downloads\Jhalla_Wallah_(Remix)_-_(MusicTub.Com).mp3"

but i did not specify path names in my code . the player has file menu from where it can open mp3 file stored anywhere in drive.
most of the songs layed but for few songs it gives this error ... how can i solve it ??
