John: Do you want to come to a concert tonight?
Jane: That depends on who's playing.
John: Oh, it's the Kaiser Chiefs with Jeff Lynne's ELO in support.
Jane: Wow! That's right up my street. Count me in!
John: Great, see you at the Apollo tonight at 7.
Note that you put "streets" in your title. That's incorrect. The set phrase is "right up my street". It basically means that it's something that really appeals to you, that's absolutely to your taste.
