Sing or Sin?

Waking up to see that everything is OK except for the sore in my throat. Thanks Goodness it's not permanent as I'm going to PartyWorld for some preparation for school diva audition. Today, I would decide on a song for the audition and strengthen my strength and correct my flaws for the song.

Here's a list of song that I will sure to sing later: (In Priorities)

1. 蒼蠅的淚滴
   
2. 数到五答应我
3. 旋律
4. 我可以

Among these 4 songs, I believed that the harder one would be 我可以 as the song consist of plenty of higher tone. I couldn't do such peak especially if the previous tone was a low one.
