First up, my favorite "I love America" song will always be "God Bless the USA" by Lee Greenwood. This song just always makes me feel glad to have been born in the US.
The second song's setting is the 4th of July, but it's really about achieving freedom of a different sort, Martina McBride's "Independence Day".
If you're in the US, I hope you have a great holiday.
Are there songs that you always think of on the 4th of July?
