All of his studio albums and EPs charted on the Billboard 200, and many of his singles —" Eazy-Duz-It ", " We Want Eazy ", " Real Muthaphuckkin G's ", and " Just tah Let U Know "— also charted in the U. S. On March 30, 1995, four days after Eazy-E's death, Tom Elerwine, a Daily Arts editor for The Michigan Daily covered Eazy's career in a feature story.

The followup single, " Never Let You Go ", failed to chart in the U. S., but did reach No. 42 in the UK Singles Chart and No. 18 in the Canadian charts.

The album was propelled by four hits, " Hold My Hand " ( U. S. No. 10 ), " Let Her Cry " ( U. S. No. 9 ), " Only Wanna Be with You " ( U. S. No. 6 ), and " Time " ( U. S. No. 14 ).
