HELP - java vs. mp3

[isee]

salve,

vabè provo a cambiare programma...magari qui sapete aiutarmi.
ho trovato un codice per la riproduzione di mp3.

quando metto in pausa la prima volta e poi faccio play, la canzone riprende da dove si è fermata. se poi metto ancora pausa e d nuovo play...torna indietro l'offset della riproduzione. xkè??
