omg this is easy! at least when it comes to arashi, for me....
"Todai Jikake no Umbrella" and "Super Fresh" are 300% better than the a-side "My Girl" (although i do love that song too, it's just that the two b-sides are the standout tracks of the single, since they sound so different than arashi's recent songs
)
and i also thought of one more.....
school food punishment - "fiction nonfiction" is also SO MUCH better than the a-side "sea-through communication" (although again, i do love that song too, lol, the b-side just simply rocks
)
(i didn't do the < or > symbols because even until today, they still confuse me 
)
