POP LP CHART : Roy Orbison LPs Go Into Orbit

<i> Arts and entertainment reports from The Times, national and international news services and the nation's press</i>

The late Roy Orbison, whose albums have been huge sellers since his death in December, may have two in the Billboard magazine Top Five next week. His solo album, “Mystery Girl,” (No. 6) may inch up to join his group effort and the fourth-place “Traveling Wilburys,” looks like it will still be in the Top Five. Superteen Debbie Gibson still heads both pop charts, with her album “Electric Youth” and her single “Lost in Your Eyes.” After 10 months of slow, steady sales, highly regarded singer Melissa Etheridge’s debut album, “Melissa Etheridge,” has been gathering steam in the last few weeks, chugging up to No. 44.

* Fine Young Cannibals are chewing up the competition. Their second album charged up to No. 32 in just two weeks.
