How should I record this demo?

[Jesse Rocha]

I have 11 songs complete, rock songs, my inspirations are Nirvana, Greenday, Led zeppelin and others...but as i was saying, im going to a studio to record them, should i record like 4 or 5 songs and give those songs to record labels? or should i record all 11 of them, i have a demo of one two of them on youtube, my Youtube username is Turbinman96, check the songs out if u like, there not even my best ones. Oh should i give the record label my best song? or no, thank you!
I have played at bars, ur the first person to tell me this, everyone else that obe talked to loved my music and what do u mean the chords need practice?
