Syntax: This is a complex sentence. The main clause is 'You put the boom, boom into my heart' with an interjection ('ooh, ooh'). The second independent clause, 'You send my soul sky-high,' is connected to a dependent adverbial clause of time, 'When your lovin' starts.' The structure is Subject + Verb + Object + Prepositional Phrase (for the first clause).
Morphology: 'Lovin'' is a colloquial, informal contraction of 'loving,' using an apostrophe to replace the final 'g.' This is common in song lyrics and informal speech.

Syntax: This segment uses simple present tense ('something's bugging me,' 'something ain't right,' 'my best friend told me') to describe a current feeling and a past event that caused it. 'Ain't' is a non-standard, informal contraction for 'is not' or 'am not.' The clause 'what you did last night' is a noun clause acting as the direct object of 'told.'
Morphology: 'Ain't' is a morphological variant representing a contraction that is grammatically informal. 'Bugging' is the present participle form of the verb 'to bug,' used here in a continuous/progressive sense.

Syntax: The main structure is an imperative sentence: 'Wake me up...' followed by a negative imperative: 'Don't leave me hanging...' The phrase 'before you go, go' uses 'go-go' as a rhyming reduplication for emphasis, common in pop music. 'I don't wanna miss it' introduces a dependent clause explaining the reason for the request.
Morphology: 'Wanna' is a common informal contraction of 'want to.' 'Hanging' is the present participle of 'hang,' used in the phrasal verb 'hang on.'

Syntax: These are two parallel imperative-like declarative sentences with 'You' as the subject. The second sentence uses a comparative structure: 'brighter than Doris Day.' 'Doris Day' is a cultural reference symbolizing brightness and cheerfulness from mid-20th century American cinema.
Morphology: 'Outta' is a highly informal contraction of 'out of.' The standard comparative form of the adjective 'bright' is used: 'bright' -> 'brighter.'

Syntax: This segment contrasts two situations using 'but' as a coordinating conjunction. The first sentence establishes a fact ('It's cold out there') and a contrasting fact ('But it's warm in bed'). The next sentence uses 'can' to indicate possibility for others ('They can dance') and 'will' to express a future intention for the couple ('We'll stay home instead').
Morphology: 'We'll' is the standard contraction for 'we will.' The adverb 'instead' is used to indicate a substitute or alternative.
