Re: Recording Artist's Singles Selection
It depends one the response of the public whether they release more singles or not. If an artist such as Kylie isn't selling much, why release more material? However, if each single is a success, then there is a chance that more will be released e.g Pink and Fergie released about 7 singles in Australia each.
For example, Kylie's album relatively did not do well in Australia hence it was promoted in overseas markets more where more singles could be released. About Britney, no promo work was done for Blackout which is why not much effort was conducted into releasing as many singles. Also, she had an album coming out in a year and all the promotion went into that album rather than continue to release singles from Blackout.
With digital sales, it's easier to release as many singles as you want now. T.I release a single each week digitally for 6 weeks last year and Taylor Swift did something similar as well by releasing multiple singles in a short time span from Fearless.
It varies in each scenario though.
