I just posted a 1 minute-long theme song that my friend and I pulled together for another friend of ours. I offered to write him a theme song for a flash he was putting together. It was an attempt at a viral ad campaign. The artist who made the cartoon isn't that great, and only used about 20 seconds of the song.
If you happen to be a flash artist, consider using it during an opening scene. It was made for exactly that. I want traffic to my songs. I need the self-esteem boost.
