The Best Concert I've ever seen (?)

I’ve never been to a concert, so I have practically nothing to say about past experiences in concerts (:/). I'm more like the kind of person that would listen to music alone in their room wearing headphones. Still, I wouldn't mind going to a concert. I've heard that you can have a great time with your friends, listening to the music you like, singing along, perhaps have some drinks or food, and even buy some souvenirs. The only problem would be the crowd, which would kinda ruin the quality of the sound. Aaaaaaaand also there's that thing about the money. Going to a concert, with all the supplies (food and drink) involved would more likely destroy my budget (╥_╥). But if we hypotethically remove the cash problem, a concert sounds like a cool experience  for everyone involved. Sadly, if we talk about my music taste, I'm not a band-fan type of guy, I'm more like a soundtrack-freak kind of guy, so I think that, in the case of soundtrack based concert, it would be unfittable for the description above or far more unaccessible. In the end, I guess I won't be going to a concert in the near future until I find the right one.
