The Adventure of Getting a Donut is this week's song-a-week. (The guy named it.) I tried to stretch myself by avoiding making the song build in intensity, which I do with pretty much everything I write, and sticking to a major key.
I had trouble coming up with riffs, and digging for them unsuccessfully cost way too much time. I also realized that my inspiration, game show jingles, aren't full songs. They're jingles! So they can actually be 1-2 riffs with a lot of empty space, unlike what we generally think of as songs.
In the end, it's a two-minute song that has parts that I left in only because I don't want this to go beyond today. (There is also half of a Carcass riff in there.) I think it was good for me, though. I just have to be better about settling for riffs earlier in the week.
