Aloe Blacc doesn't believe you have really made it in the music business until you've recorded four albums.

The 35-year-old singer insists longevity is the key to being a respected musician but he is worried new artists aren't going to get the chance to develop over several records.

Blacc said: ''I don't think you've made it in the music industry unless you've got four solid albums and maybe three bona fide hit songs from each album. That's making it in the music industry, and not many artists are going to have that chance ever again because of the metabolism of the music industry right now. It's so quick and that's just the way that the marketplace works. I'll be lucky if I get a second hit.''

Aloe worked with Pharrell Williams on his track 'Love is the Answer', which features on his new album 'Lift Your Spirit', and he admits he was pleased to be able to give the producer a chance to be involved in something less controversial than Robin Thicke's 'Blurred Lines'.

He told BANG Showbiz: ''I was happy to work with Pharrell to then give a chance for Pharrell's production to stand for something positive. At the time he told me he was working on 'Happy' so I was really excited to know that he was working on the same thing. To create music that was going to open people up to positivity.''
