And of course if your input form gives the user any help when they are filling it out, then you can run in to a problem where users choose ABBA more often than Aerosmith or Argent, (more often than they would have), based just on how ABBA is presented first alphabetically.
I got around this issue by not giving any help; the user was presented with a form with blanks for five artist and song name pairs. Which resulted in a crazy amount of typos, which I fixed “by hand” using a pretty lame interface since I wasn’t a good enough programmer to create a better way in 1996. I spent a LOT of time correcting typos.
Hey, cool to meet someone who went down a similar avenue. BubbleRings also looks like a real fun startup.
It used to be a form without typeaheads for years on Gnoosic too.
I never manually fixed typos, but I have put quite some work into making the system figure them out on its own. For example by asking people "Hey, you entered 'The Beatled' which sounds a lot like the popular band 'The Beatles'. Could it be you meant 'The Beatles'?" and then offering buttons for yes/no etc.
