Frontman Ben Kowalewicz discussed this song with Kerrang! May 30, 2009 "I'm 33 now and see a lot of people who've become really complacent. They work a job they don't like. They're with a girl they don't like. They're in an apartment they don't like anything. When you talk to them over a pint, they think they have no alternative. They can't see a way out. They're too afraid to start afresh. If people are stuck like that and don't have the courage to change things for themselves, they're going to be that 50-year-old who hates everything. I've never understood grumpy old men. It's about realizing-as tacky and clichéd as it may sound-you only live once and once you've experienced loss, things get put into perspective. You have one opportunity, so live the best life you can without causing anyone harm. Go for it. If you don't, well…you'll be 50, you'll be 60 then you're dead. I don't want to ever think 'I wish…' on my deathbed. I want to be satisfied and so far, I am."
"Whole Lotta Love" was Led Zeppelin's only US Top 10 hit, charting at #4. Many of their songs, including "Stairway To Heaven," were not released as singles, as it was considered bad form in England to make people pay for singles that were on albums.
"Lean On" was originally sent by Major Lazer to both Rihanna and Nicki Minaj's camps as a slower reggae track. After both parties rejected the tune, Major Lazer recruited Danish singer MØ to supply vocals and recorded it themselves.
