[Another] Lyric Question

[charusu]

Hi everybody,

So my girlfriend is obsessed with that Kyary Pamyu Pamyu song 「つけまつける」([PV] Tsukema Tsukeru (つけまつける) - Kyarypamyupamyu - A candy & crazy J-pop video +lyrics and I heard some puzzling grammar that I hoped I could get cleared up.

1. So first lyric: 「つけまつけまつけまつける」. Now, I know つけまつげ　means "false eyelashes", and つける is the verb "to put on" - and the first lyric is translated as "Putting, putting, putting on my falsies". I figured what's going on is some wordplay between the words つけまつげ and つける, I figure that since the end of つけまつげ and the beginning of つける are so similar that she is making a play on words and combining them into one word. Like if one were to say in English "super strong strong-arm" (I am not suggesting that one would ever say this, I just can't think of a better example), where "super strong" would be an adjective and "strong-arm" would be a verb (to coerce) - that one might contract those two to form "super strong arm". Is that kind of what is happening here? Such that つけまつげ + つける = つけまつける.

2. A little later, the lyric: 「いいないいなそれいいな」. Is that 良い? If so, why the な? 良い is an な-adjective. I don't understand.
Several options, either I am clueless, I am missing something because I am clueless, or this 19 year-old uses terrible grammar - or, more realistically, a combination of all three. Also, what's up with the lack of particles? Perhaps they are omitted to make the song "flow" better.

Any help is great!

Thanks, as always!

1)
Simply, つけま is the abbreviation of つけまつげ, a dialect/slang mainly used by young girls.

2)
Yes, that's 良い. The な is a sentence final particle, not the adnominal form of だ.

The particles を or が are often omitted also in conversations.

FYI, the lyrics was written by 中田ヤスタカ, a 32 years old man.

Thanks! So does な as a sentence finalizing particle mean the same thing as ね?

[Toritoribe]

Unlike いいね, いいな has a nuance of longing/envy. (It seems to be used more often by female, IMO.)
