AGE 26 WHERE YOU'VE HEARD HIM On the soundtrack for Music of the Heart performing ''Nothing Else''; on his single ''One More Chance'' (''My first song. I wrote it when I was 16''); on tour with Cher last fall. FAMOUS FAMILY Dad Julio; younger brother Enrique. ''My music is completely different from [theirs], but I talk a lot to my brother about different things. We learn from each other.'' COMING SOON Under My Eyes, his debut album (Epic), which features a ''hot dance version'' of Bread's ''If.'' FUN FACT ''When I was little, my father used to pull me on stage and I hated it. I was afraid of all those people.'' Did fans really toss Pop panties and hotel-room keys? ''Oh, yes. I used to pick up all the presents.'' FAVORITE ALBUM Michael Jackson's Thriller. ''It had a big impact around the world -- and on me. I played it over and over.'' WHERE HE CELEBRATED THE MILLENNIUM ''In my house in Miami Beach. It was very quiet. I was expecting it to be a little crazier.'' THIS YEAR'S RESOLUTION ''To keep on writing good music that hopefully makes people happy.''
