[disclaimer - no electronic music in this post]
I wasn't going to share this until I saw you were a singer - this piece is to me the most intuitive use of mixed meter I've seen/heard - the time signature changes to complement each line of the poem:
Also, since the topic of dancing in usual meters came up, check out Balkan dance music. The time signatures are wild. I got into a conversation with a drummer once (and really the drummer is the most important person in this kind of band, right?) and she said she learned how to drum these rapidly fluctuating time signatures by first learning the traditional Balkan dances that accompany them. 11/8+13/8+5/4 isn't so weird when you know the dance steps that would occur in each measure apparently. Of course, these are traditional social dances, not club music.
For what it's worth, this weekend I went to a conference and one of the presenters talked about unusual/uncertain meters in DAW's and notation programs. He shared the music of one of his students who wrote using JUST the piano roll in FL studio, and the student disregarded any barlines. He played some of the student's music and it was great - it had a sense of countless polyrhythms but with a rhythmic fluidity I think a lot of adult composers would be happy to achieve.
Personally, I wish DAWs were a little smarter when it came to subdividing measures - is my 7/8 time 3+4 or 4+3 or 2+5 or 2+3+2? The few times I've dabbled with this I ended up making own click tracks using hi-hat samples.
