I think the problem with this album and many b-sides albums is the lack of fluidity in the songs. To me, it definitely has the feel of a compilation cd. I also wonder if any of these songs were originally Arthur tracks (Mike's short-lived side band). If you've heard Arthur, listen to "Don't Forget Me" and "Where Did You Go?" and compare.
The combination of the mediocrity of the songs and the short length make the cd difficult to really enjoy. Sadly, when I go through my MxPx collection or playlist, I skip this album. They recorded a better version of "You Walk, I Run," on the Responsibility Single (which is selling for $100 on Amazon! I paid $6 at Hot Topic). "Make Up Your Mind" was also on that single.
If they had put some bonus featues on the cd like the new Let It Happen, I might recommend it, but overall, it's a product for the collector/die hard fan. Let's not kid ourselves, it's a b-side album which means it's not their best work, but nevertheless it's more MxPx songs for people to enjoy (to some degree).
