Pros
Unlimited possibilities for song selection
Works with any drumkit via midi usb, but I have a Yamaha DTXpressIII and it's great
DTX is in the title of my drumkit and this game
Multitudes of options if you don't want to use certain drumpads you can set it to autoplay and you can play along. You can do this with each lane, I started Drummania with Auto-Bass.
Cons
Crashes upon highlighting certain songs
It either hates me or Windows 8
Slow to load up if you have thousands of songs, but that's understandable
