2 totally different bands. they sing music thats like nearly opposing each other:
Il Divo! YAY! WOOT! (in case you dont know them, they are proof that angles exist)

and

Simple Plan. clap clap
what do they have in common? many many many things! thats if u consider 3 many.
1. they're both french
2. they both have sebastiens and davids
3. (sadly) both their sebastiens are like freaking hot! why oh why??!
take a look for yourself:
Sebastien from Il Divo ( by the way, he has voice beyond compare to any other voice in this universe. i'm not obsessive. really he does. its freaking beautiful and he's really pretty. even my sister thinks so. and she NEVER agrees with me when it comes to guys that, as far as i know, are straight)
Sebastien from sp. (even tho i lost interest in sp i have to say he's the hottest there. even before david turned gayish. yea. in p5, he was the reason why i wanted to name my future son sebastien also cause then i didn't know any sebastiens. his eyes are so dreamy~)

theres a lesson to learn from everything. and the lesson that i've learnt is (this is due to the fact that i do believe your name reflects your personality):
EVERY LETTER IN A NAME COUNTS. yea. of course i'm biased here coz i dont know their personalities but they ARE better than average!-in terms of looks, career and talent. sort of
so its either that lesson or
FREAK ACCIDENTS DO HAPPEN thats if u know what i mean
