Suggestion Box

[Kol]

Ones I just made up (some of which are totally unrealistic):
Greatest Minor Hits Tournament. You nominate some songs to the tournament host that charted in the UK (Top 100/75 - that varied over the year) or in the US (Hot 100), but did not reach the Top 40.  The rules are pretty simple after that. The host holds a number of rounds and people vote on the songs in each round. Usual terms and conditions: time limits, secret PMs for final(s), etc.

This one caught my attention, surprise surprise! 

I love the idea though it might not be easy for folk to find a list of songs that fit the criteria and if you give people too much to do it become less interesting. Of course you could have the host do most of the sourcing. 
I'm still considering running a best UK no.2 and best UK xmas no.1 contests.
