Not too bad, adding the horn is a nice touch.
I have 3 intros that I use, but they're just songs, I didn't edit them or anything.
-Viking Death March: Billy Talent
-Shoot to Thrill: AC/DC
-300 Violin Orchestra
That is one of my personal favorites to use.
I have 300 Violin Orchestra, Run This Town (orchestral version), Here Comes the Boom, and Heart of Courage from Two Steps From Hell that I like using. I also like trying to add in some other things, like putting in all of the accurate goal horns/songs, some old horns (like the mid-2000s Canucks, early 2000s Avalanche siren, Nordiques, etc.) using Cee Lo's **** You as the song when a road team scores a goal, and All I do is Win for a home win obviously.
I don't get creative and edit songs or anything, but I do like adding a customized aspect to the game.
