Bounce: Joey
Have A Nice Day: Novocaine

What Aboot Now: Because We Can, I'm With You, What About Now, Pictures Of You, Amen, Army Of One, Thick As Thieves,The Beautiful World, Room At The End Of The World, The Fighter, With These Two Hands, Into The Echo

I pretty much stopped following BJ right around Crush time but I was a huge fan growing up so I couldn't resist the temptation to chime in So, here's my list up until Crush:

Debut: She Don't Know Me (sounds sooo terribly out of place, might be ok on its own)
7800 Fahrenheit: King of the Mountain (might as well be their worst song ever - at least from the era that I'm knowledgeable about)
Slippery: Never Say Goodbye
NJ: Blood on Blood (I think this song's pretty sacred around here, so I'm sorry but I always hated the insincerity of JBJ in that song - sounds very much forced to me, the whole I'm-just-a-rock-singer-in-a-band persona)
KTF: Bed of Roses
Crossroad: Always
These Days: Bitter Wine
Crush: Thank You For Loving Me (there might be worse ones but I don't remember most of this album and I remember hating this song with a passion)

Stranger In This Town: One Light Burning
