I am a music pin guy too... see my lineup

Metallica - a must have!
AC DC - great game -- get it at a decent price play it and have fun - you wont loose out when you resell it (its popular)
KISS -- fun.. simple really... to me not much going on.. if it were not KISS music and all.. I would say its a no go! BUT the sound system and choice of songs is just a RIP!!!!
GNR - great game - fun wont get rid of but you cant play GNR after Metallica - B-O-R-I-N-G!!! ha
Heavy metal meltdown- what a gasssss! the 1980's eddie van halen finger solos as you hit certain shots.. ha - I have mine decked out!
Elvis -- what a fun game.. have mine for sale but I know I will miss it when its gone
Al's garage band- iconic game - had it for years.. and parted with it.. unique to say the least but amongst my lineup it didn't hold mustard!
Aerosmith - on the way.. my long term guess is a fun game but I bet it lacks the "pinballer person test" but the music guy will love it - the color display I cant wait

The only one I have been incue with to get and waiting and waiting is IRON MAIDEN -- the art is limitless!! the music rocks.. EDDIE as the main theme.. and well We'll see.. I will have to dump one of my A titles to make space/$ for that if it comes out!!!!

does this help? I don't know.. call it my quick music pin review, HA
