in process of trying and creating a relation playlist:track (but the problem is, we don't have physical tracks in our app)
figured out a way to connect SoundCloud tracks to playlist, made a proper association, created TrackId model, added needed methods
added playlist_show view (WIP)
added 'remove track from playlist' feature
got rid of unneeded piece of code
changed playlist to which songs are added from hardcoded to dynamically choseable
added 'delete playlist' feature
Merge pull request #1 from WebDevFromScratch/playlist_attempt

Looks good
