@ThatNerd,
Dude! Sounds great!
Ok, i'm not suggesting you can take it for granted she's into something heavy, etc.
However, your post reads like you are 'assuming' her expressed interest is invalid because of your value judgement. Allow yourself to be open to surprises. Firstly, she might just fancy you (there's no accounting for taste ; ) , but more to the point, a glint in the eye, a warm smile, humour, common understanding or good old chemistry are what real attraction is about, i hope.....
Good luck, and remember, Fortune favours the Brave!
