Questions

Hi! I just have some questions on Japanese.
Thanks in advance for helping me. I appreciate all you guys going out of your way to clear try and clear up all this confusion for me ^^

So, first off is the Japanese word 'Mitai na'. I know that it means 'Looks like' right? And it is an adjective. However, I was watching a Japanese drama and there was a girl who would always say it at the end of the sentences. I've never seen it used at the end of sentences until I saw that show. For example, she would say "きょたろくんは私が大好き！みたいなーーー!!!"
Meaning "It appears that Kyotaro kun loves me!" I know that it is for sure casual language. So if that's the case, what other things in Japanese can I do to just make it sound more conversational?

Second, can someone explain this sentence to me?
音楽をかけたらって意味かと思った！笑
I know that it has music, meaning, and thought, and call. The other words like って or the か after meaning I don't understand. It's a message from a conversation between me and my Japanese friend.

Third, in conversational Japanese I notice that particles can be taken out. Should have been in my first point but oh well. Curious, do you guys have a list of Japanese conversational vocab? And when I hear Japanese words for the first time that aren't proper, for example majide isn't proper, is there any way I could try to know what means?

Colloquial words don't translate well into English as it is context dependent. みたいな prob can be translated as 'something like that'

音楽をかけたらどうという意味かと思った is what I think the full sentence is but without context it's not a guarantee. Japanese tend to omit whatever is implied in context.

I thought what he/she meant was how about you put on some music on.

As for leaving particles, happens a lot but not recommended for learners as it means you will never learn actually how to speak proper Japanese which will eventually bite you in other ways.

Convo vocab or 流行り言葉 tend to change every year so kind of pointless. Google is your friend.

There are grammar constructs though such as って meaning という, leaving out い in ている, too numerous to list.

Thanks! I like posting here haha
