Jay-Z VS Oasis?

Here's the backstory on their tiff: Earlier this summer, a reporter asked Noel Gallagher, of the British rock band Oasis, what he thought about hip-hop artists being invited to perform at Glastonbury, the famous music fest.

Noel said hip-hop was "wrong" for Glastonbury. Jay-Z got teed off.

Then in a tit-for-tat move, when Jay-Z took the stage at Glastonbury, he sang a mocking, off-key cover of Oasis' biggest hit. (Video of the performance later became a huge Web hit.)

But the two singers made some play-nice moves. Gallagher said: "I like Jay-Z." Jay-Z said he wouldn't mind working with Oasis. OK, everything's fine.

Or is it? Cut to last week. Jay-Z took the stage with Kanye West at Madison Square Garden and performed "Jockin' Jay-Z," a track from his upcoming album. In the song, Jay-Z takes more swipes at Gallagher, such as: "That bloke from Oasis said I couldn't play guitar / Somebody shoulda told him I'm a f****** rock star."

Jay-Z has had other well-publicized feuds. Past alleged blowups have been with fellow rapper Nas, record executive Damon Dash and R&B star R. Kelly.

But Web searchers don't just want to know who Jay-Z is mad at
