The [artist id="2088128"]Jonas Brothers[/artist] have a seemingly endless pool of ladies to write about in their songs of young love. Nick, for instance, wrote [article id="1613739"]the song "Before the Storm" about Miley Cyrus[/article] (which also features the "Hannah Montana" star), and now Joe has gotten in on the act, writing "Much Better," presumably about his ex [artist id="2389485"]Taylor Swift.[/artist]

That song, however, is not a good-natured duet.

"We went through a lot in the past year and a half, all of us," Joe said about "Much Better," which name-checks Taylor's song "Teardrops on My Guitar." "And you're just going to have to get the record and figure it out for yourself."

If you have any doubts about the song's inspiration, here's a sample lyric: "I got a rep for breakin' hearts/ Now I'm done with superstars/ And all the tears on her guitar/ I'm not bitter."

Joe said he knows that fans will be listening to their new album, [article id="1613921"]Lines, Vines and Trying Times,[/article] trying to figure out which songs are about which girls. "I think that will happen until we're 60 years old," the middle brother laughed.

Taylor and Joe have been battling it out in song for quite some time now. Last fall, when Swift released her album Fearless, she included the [article id="1599032"]Jonas-inspired song "Forever & Always."[/article]

"With this situation, I feel like I owed it to my fans to be like, 'Look, it happened, you weren't crazy,' and address it," she told MTV News of their high-profile breakup. "And I addressed it, and, you know, that's a chapter in my life that's closed now."
