I mostly collect shit that I get at work, mostly guitar picks. I have quite a collection of picks from different bands. I normally only keep the ones that have the artist's name printed on them, but sometimes I'll make an exception if it's a pick that I know for fact that it belonged to a certain artist. For example, I only have one white, unmarked thumb pick that I saw Joe Walsh drop next to his microphone before he walked off the stage. Another example are my Ted Nugent, Bob Dylan, and Brian May picks. They may not say the artist's name on them, but they're the only picks of their kind in my collection, and I saw the artist drop them on the stage before walking off. Currently I have about 200 picks in my collection. Some of the picks that I have include Billy Idol, Guns 'n Roses, Aerosmith, Alice in Chains, Velvet Revolver, Rob Zombie, Godsmack, System of a Down, Shinedown, John Mellonhead, Green Day, Jackie Green, Jonas Brothers, Pat Benatar, Thursday, Rise Against, Steve Miller, Night Ranger, Doobie Brothers, Black Label Society, The Eagles, Toby Keith, Tim McGraw, Keith Urban, Megadeth, Poison, Train, Foo Fighters, Counting Crows, Black Crowes, Yeah Yeah Yeahs, Bob Dylan, Marc Anthony, Ted Nugent, Sheryl Crow, Queen, Van Halen, Smashing Pumpkins, Black Eyed Peas, Deep Purple, Craig Chaquico, Jeff Beck, Down, John Scofield, Bruce Springsteen, Kenny Chesney, and many, many others.
I also collect some set lists. Not all the set lists that I find, as that would be quite overwhelming, but just for the bands that I really like. They serve as decorations for the walls in my room. I currently have The Police, The Rolling Stones, Smashing Pumpkins, the Cure, System of a Down, Beastie Boys, Cafe Tacuba, Aerosmith, Rob Zombie, Godsmack, Marco Antonio Solis, Deep Purple, Billy Idol, Green Day, Roger Waters, and several others on display in my room, though I might do a revision in the near future.
