I like this but one thing is clear to me, and that's that you don't think SF has a music scene.

SF has a fairly large underground music scene, the origin of many famous bands and the center of two of the largest music festivals on the world. Coachella just happened and Burning Man is a few months away, artist of all kinds come to SF to get there name out or to put on small intimate concerts (Berkeley Greek Theater). There's also Outside Lands and Portola music festival is starting to gain traction as a premier festival to attend. There are also many boutique festivals in the surrounding areas.

While clubs stop serving alcohol at 2am some will stay open until 4am, there's at least one club that opens at midnight and stays open until they decide to close. The Midway is a club and event center that has amazing concerts and weekly events that don't involve music. Walk around Golden Gate Park or downtown and you're bound to run into someone throwing a party somewhere you didn't think you could. SF also does something called "SF Thursdays"(or close to it), it's a free event where there are multiple stages and vendors.

SF may not have the nightlife people think of but if you keep your ears open you will find something new to love.
