Whether or not you enjoy every track there is always a worst one.
It's the one you like the least.
For example, if I like doughnuts, hot dogs, and pickles, but am only allowed to pick two of them for a lunch, I would pick pickles and hot dogs. It's not that I don't like doughnuts, it's just they would be my least favorite between the three.
There has to be a track that one would consider the worst, which could be the one you like the least.
There. That was bothering me.

* ), I do think Tats will rank higher than Ringtone, WYL, and CraigsList.
