I personally just go out and make my own. I have had Spotify since it came out. Some 200 playlists. I would say go out and make your own. They have a great Discovery zone, just make sure you upvote songs you really like.
Also if you pay for it, no adds, you can download playlists for listening when there is no internet, and lastly the best part of paying. You can increase the sound quality if you dig into the settings.
