Lyrical Charades

Being in love is like hearing your favorite song for the first time.
It starts out slow, and you're not sure what you think of it.
Then the rhythm of it gets into your soul, and before you know it, you're singing along to lyrics you've never heard before, and know every word.
You're so excited that you had your radio tuned to that channel at the precise time the song that changed your life began to play itself out.
Then, it starts to near the end.
And, you're so glad you heard it, but you're not ready for it to be over.
The ending is so heartbreakingly confusing because:
What if you never hear it again?
What if you don't know where to find it?
What if it's not the same the second time?
And then, it's over.
And you know that it's changed you.
Your outlook on life.
Your heart.
