Take the drums so that you can jam along! For example, let's say Rush provided you with an MP3 that had your favorite song on it, but with no drums...
Now... mic up your kit and run it and your iPod into a mixer and put on the headphones... now you are jamming with the band. Now you ARE the drummer for Rush.
For example:
That's me drumming (poorly) to a "drum-less" track I wrote.
So what I'm asking is if you could have any track without the drums to jam with... what would be your favorite song?
