Answer:
This question is incomplete and I could not find online the song to which your question refers, but anyway I will give you an explanation about the conditionals that will help you to understand this.
Explanation:
Conditionals are used to speculate about what might happen, what might have happened, and what we would like to see happen.
Most sentences that use the conditional tense contain the term "if".
There are four main ways to construct conditional sentences. In all cases, they consist of an "if" statement or clause and a main statement.
Next I will write the types of conditionals that exist, their use and the structure they carry:
- Conditional Zero: General Facts
if + simple present, simple present
- First Conditional: A possible condition and its probable outcome
If + Simple present, simple future
- Second Conditional: A hypothetical condition and its probable outcome
If + Simple past, Present conditional or Present continuous conditional
- Third Conditional: A non-real condition from the past and its probable outcome in the past
If + past perfect, Perfect conditional
