What does 二周目 mean?


I find this all over the net, but can't find it defined anywhere.

I'm trying to understand this tweet:

じゃあ二周目は是非モノマネで♪( ´▽｀)RT @mimiroll_410: @mao_sid
今友達とカラオケに入ってるシドの曲を五十音順に全部制覇しようとしてます！(笑)ちなみに今は土曜日の女です＼(^O^)／

What does the first sentence say?




目 is used as an _ordinal_ suffix. ~~It's the difference between "2 weeks" and
(like in this case) "the 2 **nd** week".~~

**Edit:** Sorry for failing so blatantly. :( Updated answer, now with less
obvious errors!:

So in this case, Mao is suggesting that "the second _round_ " be Sid
impersonations (the first "round" is singing all the Sid songs in the Karaoke
machine in alphabetical order).
