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?

question
translation
What does 二周目 mean?
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).

Needs more context. ～周 means "(a) round" or a "cycle" or a "revolution". So if
you're talking about a race (horse, car, etc.) it would be the 2nd lap. Since
a "cycle" of a business, establishment, etc. is usually a year (the length of
one revolution around the sun), it can also mean 2nd year the place has been
open for operation. Or just at iteration number of some regular event; the 2nd
times it's happened.

**EDIT** : I'd say the first sentence says, "OK, round 2 will be
impersonations (of people)."
