-#### I get system cannot find the specified file when downloading?

-#### How can I download whole playlist with its URI?

-~~Currently this is not possible without generating unique tokens from Spotify but you can copy all the songs from a playlist and paste them in `list.txt`. I am avoiding tokens as much possible to retain the portability of this tool but if you would like to add it as an optional feature to this tool, PR's welcome!~~
