"The submission should be over minute long, but this rule is flexible. Just be sure your composition is complete and not just a snippet or a work in progress."

Sounds like it's already flexible! More of a guideline and a minute is very short anyway.

Collab with my partner, https://luna-and-the-spacebaes.bandcamp.com/
Still need to make one for my own stuff.

Share alike is a creative commons thing which means people can share and remix your work provided they allow the same

Write a share-alike song, next week, remix someone else's song.

Instrument limits. eg (use only 2 instruments)
Fixed chord progression. eg. use iii ii V I i
Fixed scale eg. use harmonic minor
Fixed time signature eg. use 6/8 time
Fixed tempo
iron chef style ingredient of the week: eg. must use maracas or trombone

lots of possibilities, could add lots to a spreadsheet and randomly pick one each week

obviously if you don't like it, you don't have to use it, but could be a good starting point if you're stuck for ideas

How about a new random constraint each week for extra fun?
