What is the craziest thing you've done as a musician? Stuff like writing an insanely long song or album or using unusual things as instruments and stuff like that or anything else you can think of that relates to your writing process.
For me it used to be the fact that I have an album planned that is 100 tracks long (106 including bonus content) which is supposed to be at least 7 hours long because I don't like writing songs shorter than 4 minutes. It wasn't something I had planned. It just so happened that I wrote this many songs in that period of time which is the theme of the album (my life from late 2K10 to 2K12). I have other albums that are pretty long as well—in fact my regular albums range from 20 to 40 songs.
That used to be my longest planned album because now I'm in the process of writing 500 concept tracks (+20 bonus tracks) for this year's album. The number is symbolic for several reasons and I've upped the challenge of the first long album which is kind of fun (even though it will take me at least two years to finish this album alone).
