Rapper French Montana has canceled the planned release of his Mc4 album.

The star's second studio project was scheduled to hit retailers in August (16), but it was pushed back to 14 October (16). However, the music has now been shelved due to issues with sample clearances.

French Montana previously released four songs from the album, which reportedly featured collaborations from other rappers including Kanye West, Drake, and Nas, but he was unable to officially share other tracks and didn't want to put out the disc unless it was complete, even though some tunes had already leaked online.

"Songs like I'm Heated and Two Times couldn't be cleared," he tells Complex. "By the time I got the mix how I recorded it, it wasn't the same. I just ain't (sic) have the same feeling for it. Everybody had to replay s**t, and do all this extra s**t, so I wasn't in the mood to put it together. All the music going to come out (sic), you know what I'm saying, just packaged differently. Plus, the album got leaked."

The rapper is now working on completely new material, which he reveals is "about 70 per cent done", but he will not be sharing many details about his songs this time around because he wants to ensure all the music is cleared first, while he also doesn't want to risk any leaks.

And French explains he is more concerned about a smooth debut rather than setting a release date.

"Let me tell you something: I'm never married to a date," he continues. "I got 17 mixtapes I put together, and one album. That's 18 projects in my whole career. I'm never married to a date. I put it out whenever it's right. You could force yourself to make it to that date, but if it's not right, (if) it don't come out right (sic), you can't force it."
