I do, a lot. I use an old Winamp plug-in called iZotope Vinyl, which I think replicates the sound of vinyl records quite well. I like to play "Stairway to Heaven" by Led Zeppelin or "Warning" by Black Sabbath with most of the vinyl effects turned up high. Especially the warping on the acoustic guitar sections, makes the song sound rather ominous.
So, who else is a fan of the low fidelity sound?
