Singing In Line

I spent a lot of time submitting music videos to the music database on Inleo today. Consequently, I have been
thinking about songs all day. I've always enjoyed singing. Some songs stick in my mind, while others require a lot of work for me to learn the lyrics.

I thought I would record some bits that give me trouble while I wait in line to pick up my daughter from school. All of these songs are in Spanish.

NOTE: My first upload was cut short for some reason. I didn't catch it until after I had already posted.

Watching myself sing, it seems I need to open my mouth more. I think that is probably contributing to my trouble with some of the songs. If you know any exercises or have recommendations that could help, let me know in the comments.
