Another Day, Another Song! Let's Go~
Melissa by Porno Graffitti (Full Metal Alchemist)
To be honest, for me the most memorable song from FMA is Again by YUI (You can find it here). However, this "Melissa" is the most enjoyable. I love that classic J-Rock and the memories...so many memories. These guys have been in the anime/gaming scene since 1994, still rocking, and have countless songs throughout this industry.
This song and "Again" is what made FMA so enjoyable for me and one of the first times I liked an anime song this much and one of the reasons I got into anime music all together. That guitar solo just brings nostalgia and I really can't get enough of it. Unfortunately, we don't see many songs like this nowadays which is bummer but someday we will get them back.
