Jamming project altered

Hi, this is my version of Jamming project:
I’m still working on a few things like delete a list or play preview of a track…
Because we’re fetching Api in Spotify.js module its a little difficult to make user logged by clicking on a
link ‘log in’ only once, first the Spotyify log in window is triggered and data fetched and the function logIn() in App.js stopps running, only second click actually sets the state and on that bases ‘log in’ is switched to ‘log out’, well something to work on…I hope you guys still like it. I will welcome any feedback, thanks
