Do you ever feel bad when you think about how much you've spent?
I think that this can be said for anything really when you stop and think about how much you spend a month or year on starbucks, cell phones, muffins, lunches, chips, cookies, cheeses (i kid you not...my boyfriend spends a fortune on all these weird expensive cheeses... one cheese he brought actually had a security tag that goes off if it's not disabled by the cashier!!) etc.... Everything does add up.
We all deserve to have some nice stuff once in a while, there's nothing wrong with it. It might be another issue, if someone is in debt and still on a spending spree with pandora then that might be a problem and remorse might start to kick in.
