challenge 1 cold start problem ; playlists doesnt have any tracks : proposed solution is based on playlist name; 
- find similar playlists 
- find most played artists in these playlists
- find their popular tracks
- select these tracks as seeds for cold start playlists
challenge 2 sparsity problem; playlists have  less than 10 tracks: proposed solution is; 
- calculate the next track based on lstm sequence probabilities for each track in whole given playlists.
- get 10 track candidates for last track in playlist
lastly, create sparse matrix which is including seed tracks and run implicit matrix factorization.
