Why do they have to ruin the things I love?

I've been listening to a load of music recently. I've become obsessed with bands and decided to look into some of their history.
I've noticed that a lot of bands that I like are either breaking up, loosing a few members and their sound being destroyed, or just completely changing their style of music.
I'll provide some solid examples.

• A year or two ago, I started listening to My Chemical Romance. I loved their music and listened to it for days straight. A few months ago, they broke up. It wasn't so much sadness that completely ruined my life, but just the crushing realization that they would never, ever make any new music again.
• I felt kind of disappointed when I realized Formulas had broken up.
• I was never much of a fan of Panic! at the Disco, but I don't really like their new music and I'm kind of sad.
• Paramore! Oh my gosh. They lost some band members and then they completely changed. It's like you can hear the absence of the Farro brothers. Zac was a really talented drummer and...ugh...I may continue this later.
• Shine Bright Baby was a fairly good band, I really liked some of their songs, then I heard Beautiful Love and felt very strange for the next few hours.
• I'm making the text really small, but Avril Lavigne's 3rd, 4th, and most of her 5th album just really disappointed me.
• And 30 Seconds to Mars, not as sad because I wasn't as attached, but just disappointed.
• Also, the guy who did the screaming in We Are The Ocean, I think he either quit the band or was kicked out.

I know a lot of people can relate to this. But just remember, it's alright. There are other bands, and feel free to rape the replay button :)
