Programs for gaining likes on Facebook fan page? (etc: commenting groups, messaging, etc)

I just made a new Facebook fan page to promote my music. I'd like to gain a lot of likes on the page obviously and was wondering how I could do this? However, I'd like some suggestions to gain real likes from real people only. I've used bots for other social media sites that send out friend requests and automate other tasks within the site to gain exposure. do any of you know about any programs like this, but for Facebook fan pages? i'm willing to pay for it. If any of you have any other ideas on how to gain likes on a fan page that are simpler or do not have to do with programs please let me know.

Thanks!
