Search Results: find a name with a phone number

Nut-shell version: Met a guy at a party (not sure if the flirting went as well as my booze memory said it did), exchanged numbers, should I wait for him to make the first move or what?

Extended version: I tagged along with a friend to a very chill drunken hangout session. She liked the guy hosting (we were the only two girls there). I remember really flirting with a guy that I met and discovering we both liked some of the same really unique music. (This was Sat night, it is now Mon). When we started talking about music he said there was no way he'd remember all the artists I was suggesting, so I gave him my number and told him to text me sometime. He called my phone and gave me his name so I could save it. I don't know if actually saved mine, but he at least put it in his call log. The next day he and one of his friends added me on Facebook. (Everybody was awesome that night, so much fun!) The problem is I don't know if it was booze or more, and if nothing else I'm super excited to find somebody who likes the same music as me. (aka I'm not necessarily looking for a relationship, so much as a music buddy)

So.. Should I wait on him, should I text him, shoot him a Facebook message, or just chalk it up as an interesting evening?
