Same, I had to do it. The era when bundles were everywhere took its toll on my library -- I redeemed near enough every key I had. Had to do some store page checking to see if I was ever likely to touch a lot of games, and the answer is a resounding "No". I've got 63 games in that category, which I like to hope was all bundles and so doesn't quite translate to wasted money...
For anyone that might want inspiration, my current category list is:
1. In Progress
2. Next In Line
3. Not Started
4. Finished
5. Abandoned
99. Won't Play
