For those who remember Howie Day, this is pretty cool. He was a big deal in the 2000s. He's mostly known for his hit, "Collide." He sells a bunch of signed stuff on his etsy page, including hand written and signed lyrics to his hit Collide for $175 or a waveform of his songs with a hand written lyric and signature for $60.
