Ok, some constructive criticism, nah, just criticism...
Firstly, were you actually doing a music survey? To me it seems like some canned pick up line that is really bad. It's a script, you're not being real, you're not being yourself. So be genuine, give off warmth, smile. The simple thing to do is say "hi, what's your name?" ..."Hi, I'm ElStud"..."I'm looking to meet new people/I want to meet you" ..."Are you single?" ..."Cool, write down your phone number, oh, and write your email too." "Bye/See ya/TTYL"
Would you want someone to bother you while you were on the phone? Bad idea dude. Remember, don't approach from behind. And most importantly remember your posture, body language, eye contact, smiling, dress, cleanliness.
You don't have a girlfriend, you're a lying sack of crap, and then you ask them for their number and say you have a girlfriend, oh man, the logic is intact. They probably see right through your BS.
The whole approach is akward with a captial 'A'.
If what you're doing is not currently working, then try something else. No one said this was going to be easy. Yes you have the balls and courage to approach, but you can't just rush in and try to attack the problem with pure courage, you also need smarts and strategy, you need to know what you're doing.
Stop the whole music survey gig and "I bet you go home upstairs and rock out."
Good luck.
