Bon Jovi's last two albums both hit the top of the chart, and now it looks as if the group's leader may do the same with his first solo release. Jon Bon Jovi's Blaze of Glory, a set of songs ''inspired by the film Young Guns II,'' shoots up to No. 7 after only two weeks, leaving Madonna, Depeche Mode, and Billy Idol in the dust. Meanwhile, M.C. Hammer holds on at No. 1 for the 12th week-a feat last accomplished in 1988 by George Michael with Faith. LAST TOP 10 POP ALBUMS WEEKS ON WEEK CHART
