If it weren't for Rock Band 2, I would have never gotten The Beatles: Rock Band.

If I hadn't played The Beatles: Rock Band, I would have never sung "I Want To Hold Your Hand".

If I hadn't attempted to sing "I Want To Hold Your Hand", I would have never known I was mixing up the lead and harmony vocals at the end of each verse.

If I weren't so bothered by the fact that I was incorrectly singing one of my favorite Beatles songs, I would have never searched for a solo rendition of it on YouTube.

If I hadn't been so dissatisfied with the initial search results, which gave me awful covers of the Across The Universe version of "I Want To Hold Your Hand", I would have never seen this video of T.V. Carpio singing it...

And if I hadn't been so taken by the video and T.V.'s singing, I wouldn't have added Across The Universe to my Netflix instant queue for viewing later today.
