I hate talking at the beginning or end of a perfectly good song. Shut the fuck up. I don't mean at concerts, though that's often annoying too; I mean on the studio-recorded tracks off the album. I don't wanna hear your stupid little intro, I don't give a shit who the song's dedicated to, and I certainly don't care to hear your god-awful spoken-word poetry you think belongs at the end of a song for some reason. I'm paying for your music. If I wanted to hear someone talk without listening I'd call my mom or my ex-girlfriend.
You want to dedicate a song or write a poem? Do it in the liner notes. What was that? No one reads the liner notes anymore? That's because you've been filling them with meaningless dedications and shitty poetry, and, as stated earlier, people don't give a shit about your dedications or poetry. So keep them out of your goddamn songs!
