Breaking Bad - Mini Spoiler on Season Opener

I guess it doesn't really qualify as a spoiler, but apparently the song "Truth" by Edward Sharpe & the Magnetic Zeros will be featured in the season 4 opening scene:

The upcoming fourth season opener of AMC's "Breaking Bad," however, will feature Mr. Ebert's song "Truth." That wasn't an easy decision, either, for Mr. Ebert. "Kind of promoting meth use is something that he had a hard time with," Mr. Ling said. "We had to look at the scenes and see how it went down. He had to do some things to get OK with it."
