I have to disagree on your last point on if you want to support the album you have to buy it. Some people can't afford to buy it. You can do other things such as listen to the songs on Youtube or call into radio stations to get them to play the songs. Buying the album isn't the only way to support Harry and his music. You may not really have meant your comment that way, but I just wanted to give my two cents.
This is very true and wasn’t meant as a slight to anyone who doesn’t have the financial means to buy the album. There are loads of ways to help out, and steaming, tweeting radio stations and reblogging posts all help.
But if you DO have the means, and you WOULD buy it (and you say you’re sure you’re going to like it), but you think everyone should be allowed to do what they want with their money, so you’re going to support the album by LISTENING to it when it comes out? Yeah, that’s not really support.
