The 2008 Great Lakes Songwriting Contest is now accepting entries, either through submitted CDs or through Sonicbids. The cost per song entry is $25.00 CDN or US (although now that the Canadian dollar is actually higher than the US dollar at times, that's not such a bargain anymore) and you can find the full rules here.
You can find the list of the 2007 judges here. They included Toronto's Jodi Krangle from Muses Muse (one of my favourite songwriting website resources) and folk band Urban Tapestry, Detroit funkster Nadir of the band Distorted Soul, and Minnesotan Andrea Stolpe, a professional (former staff) songwriter who provides e-learning courses on songwriting on her website. The list of the 2008 judges remains a mystery (until the winners are declared...)
The deadline is April 25, 2008... see you in the Winner's circle :)
