If you listen to the radio and think you hear more lust than Les Paul, you're right. A new report on songwriting trends shows that synthesizers and sexy lyrics are much more popular than guitars and romance in today's songwriting.

A whopping 79 percent of charting pop songs cite the synthesizer as their primary instrument, The Hollywood Reporter says, while guitars are down to an all time low of four percent. The reason guitars are losing ground? Rock radio is, too. Rock songs only comprised 8 percent of top ten hits, while dance and club music -- most of which is synth-based -- comprised 50 percent. Hip-hop came in second place with 21 percent.

In what may be a sign of the times, lyrics about "hooking up" were in 38 percent of hit songs (we're looking at you and your disco sticks, Gaga!), while love songs trailed with 17 percent. Inspirational tracks ('Firework', anyone?) were the second most popular at 25 percent, followed by songs about partying (a la 'Last Friday Night') at 21 percent. The ever-ambiguous 'other' comprised 0 percent of hit songs -- last year, it was 9 percent. Are our heads that deep in the gutter?

Some good news for female musicians: The girls have almost just as many hits as the boys do! Last year, male vocalists were showcased on 57 percent of hit songs. Today, men account for 46 percent and women for 42 percent of hit songs, with duets filling out the rest with 12 percent.

The report lists Adele's '21', Lady Gaga's 'Born This Way' and Nicki Minaj's 'Pink Friday' as the best-selling albums of 2011, with the year's biggest hit singles including Black Eyed Peas' 'Just Can't Get Enough,' Jennifer Lopez's 'On the Floor,' Katy Perry's 'E.T.,' Pitbull's 'Give Me Everything,' Rihanna's 'S&M' and LMFAO's 'Party Rock Anthem.' These records are pretty consistent with the patterns and themes -- especially about partying, hooking up and the popularity of duets -- within the study.

The popularity of certain songs and their subjects can certainly reflect on our psyches, so these findings are interesting in more than just charts and singles sales. It seems like listeners just want to dance and have a good time -- and that's pretty timeless.
