Meghan Trainor's "All About That Bass" jumps into the Top 20 on iTunes. AJR's breakthrough and Iggy's latest continue advancing.

Based on the latest iTunes sales chart movement, music buyers are very appreciative of self-appreciation.

Meghan Trainor’s empowerment anthem “All About that Bass,” which continues to explode at Top 40 radio, recently reached #20 on the iTunes Single Sales chart.

With buzz unrelenting and airplay only set to increase, “All About That Bass” seems poised to leave a meaningful mark on the music world this summer.

Colbie Caillat’s thematically compatible “Try” is also moving at a high volume on iTunes. The song, which drove a record 850,000 downloads when offered as iTunes’ Free Single of the Week, is positioned at an impressive #22 on the iTunes chart. It is no longer free, but its message is still resonating.

Other notable movement on the leading digital retailer’s overall single sales chart:

— Becky G’s “Shower” and KONGOS’ “Come with Me Now,” which cracked the Top 20 in time for last week’s update and are also among pop radio’s twenty most-played songs, continue to perform well commercially. They rank at #15 and #17, respectively, on iTunes.

— AJR’s enduring “I’m Ready” continues to pick up steam. The song, which has been gradually advancing on iTunes since its spring radio impact, is now #25 on the chart.

— Proof that iHeartRadio is onto something with its “On the Verge” picks, Clean Bandit’s “Rather Be (featuring Jess Glynne)” continues to resonate with music buyers. It is #26 on iTunes.

— It is not as hot as her “Problem” collaborator Ariana Grande’s new single “Break Free (featuring Zedd)” (#16 on iTunes), but Iggy Azalea’s new single “Black Widow (featuring Rita Ora)” is rapidly gaining ground. It is #35 on iTunes.

— Shawn Mendes’ “Life of the Party,” which reached #1 upon release earlier this summer, is still making noise. It is #36.

— Echosmith’s “Cool Kids,” which had just cracked the Top 50 in time for last week’s update, is now #46. It had double-digit add weeks at both Top 40 and Hot AC radio.
