To my mind, if sex is used to sell songs it shows:

i. the poor quality of the music
ii. the lack of talent of the singer who cannot rely on the music to sell itself
iii. the lack of imagination of the manager
iv. the lack of ability of the audience to see a singer (male or female) as an actual person, but only as a desirable object
v. the willingness of the 'artist' (ha ha) to make use of this
vi. the poor state of the general public who are taken in by this shite
