So here are SOME of my favorite Glee Cover :
1. Misery by the Warblers.
I just don't know, why everytime they'll cover a song, I usually get addicted to it.
2.Teenage Dreams by the Warblers.
When Rebecca Black released this song, a lot of people gave negative feed back about it, but that moment when I heard New Horizon covered the song, I wanted to hear it again and again.
Ever since, I knew about Jar of Hearts, I couldn't let a day pass without hearing the song. But when Rachel covered it, O__________o my heart flew, and I love Glee more!
So far, I only enumerate my Top5. Enjoy listening to your favorite Glee-covered songs. :)
