A guide to singers you can't sing along to without at least trying to imitate their voice, ranked from 10 to 1 in order of how impossible it is to NOT try to imitate them:
Moment You Definitely Have To Imitate: Shrill-ly yelling "WANNA GO FOR A RIDE?" in "Zero"
Bonus Tip: If you're doing group karaoke, flip out and kick the other people out of your group, then turn up your mic so it's the only thing anyone can hear. But still call yourself 'Smashing Pumpkins.'
Moment You Definitely Have To Imitate: The "Weeee look at each other" part in the opening verse of "Ants Marching (i.e., "She thinks, H'weeee look at each otheaarrrrr, WON'dring what. Theee other is theenking...")
Bonus Tip: Slur your words with confidence and no one'll question the fact that you never learned the actual lyrics, just their general sounds.
Moment You Definitely Have To Imitate: The echo-effect on "sky" in the opening verse of "Sweet Child o' Mine" ("Where eeeverything was as fresh as a bright blue skYYYYeeee... skYYYYeeee... skYYYYeee...")
Bonus Tip: Once you realize that "Paradise City" is 7 minutes long and you don't know any of the verses, just storm offstage and it'll merely add to your gritty, rockstar mystique (for about a year).
Moment You Definitely Have To Imitate: The elongated "care" before the choruses in "This Charming Man" ("This man said it's gruesome that someone so handsome should caaaaaaaauuuuuuuuuuhhhhhhhahahhhiiiiihhhhh" [Followed by a well-timed AHH!]")
Bonus Tip: Emphasize every word like it's the most important word in the sentence / universe. This will somehow sound good, inexplicably.
Moment You Definitely Have To Imitate: Long, yelly overemphasis on the last word in every chorus lyric in "You Oughta Know" (i.e., "It's not FAAIAAIAH, to remind MEEIAHH...")
Bonus Tip: If you're choosing this song at karaoke, definitely feel free, just know that you're not the first person who's sung it that night. Might wanna go with something less expected, like "Like a Prayer" or "Don't Stop Believin'".
