I've been looking for fics like this one http://lostt1.livejournal.com/316410.html
"Jensen has been in love with Jared for years. The problem: Jared is his best friend's little brother. The solution: Jensen moves to California and writes songs for popular pop artists. Every song is about Jared. But what happens when Jensen finds himself living with Jared after six years apart? Will the balance he's found fall apart or will he finally get the one thing he's always wanted?"

So, in short, fics that have one of the Js writing songs about the other, or fics that have the one of them being older than the other (high school, college) and pining.

Thanks!
