You guys are acting like Warner's marketing tactics are somehow worse than LP doing it themselves. I guarantee you that if LP went independent after their contract was up, you'd never hear another new LP song on the radio ever again.
That's the reality of big-name labels - the marketing machine. Warner can throw millions of dollars into marketing for LP - they just didn't, for whatever reason. Has LT even gone gold yet?
If LP split from Warner, in order to keep themselves relevant they'd have to sign with another label. Going independent isn't an option for them, unless of course they want to be that band that sells less than 100,000 copies of each of their future albums for the diehards.
