How to start a conversation

So i did meet someone on this dating app thing that i have never used before as we both liked each other (i think partly because we had 7 interests in common) and now i do not know how to start a conversation since i have never dated 1 person in my life. Kind of nervous if i'm honest. So how would i start a conversation as i know something like "Hey" or "How are you doing" would sound boring and way overused. If it helps here are some of the common interests that i think i could talk about : - Nirvana - Queen - Linkin Park - Guns N Roses Pretty much listening to music and bands. If you have any ideas that could sort of make me stand out from the usual hey or how you doing starter then i would appreciate it. Thanks

Well, well done on meeting someone you like. It is a great feeling :) And it depends.. are you a boy r girl? and What age group do you fall inot?
