It was just a year ago that I didn't expect STP to make an album, much less stay together, much less have a single to reach the top of the charts. If anything, we should all be very happy they've been able to do that much.
Between The Lines was definitely their cash cow for this album, but I can see where it would limit the sales. Take A Load Off is a good single to release because it will reel in the "meat and potatoes" STP fans. It's the bridge between their earlier work and this album, whereas Between The Lines is an STP that a lot of people don't understand. This is what I think their mentality is behind releasing it. However, this single is in desperate need of a music video, because that's what people respond to more these days, and it needs to be something that showcases the actual band a little bit more. Though BTL was cool, newcomers really don't know wtf is going on...
If it was my choice, I would've released these songs as singles in this order:
Between The Lines
Hickory Dichotomy
Take A Load Off
First Kiss On Mars
