You take one now and...
the other two last you forever.
Does 'last' mean when they are gone, or when you'd normally take another?
If you take one now, then one every 30min, they're gone in an hour... but your next pill would be due in another 30min.
I also think you are right to point out that there is already a lot of music out there with real content. I agree with you as well- the reason I posted this is not because Macklemore is my favorite artist, indeed he is not, but because I think his music has the chance to infiltrate popular culture. Hopefully it will open people up to the idea that better music out there.
