Call it the Cher effect.

OK, so she’s only part of two songs in “Mamma Mia! Here We Go Again,” but her presence surely helped the soundtrack blast into the Top 5 on the Billboard 200 album chart.

Additionally, her duet with Andy Garcia on “Fernando” is sitting at No. 30 on the Adult Contemporary chart (as you might guess, this is Garcia’s first entry on the Billboard charts).

If you haven’t heard this new round of ABBA tunes remade for the hit “Mamma Mia!” sequel, or seen the film itself, we can help with that.

Thanks to Universal Pictures, I have 10 movie passes and 10 accompanying soundtracks to give away. Each pass is valid for two people, Monday through Thursday, at any Atlanta Regal location.

To enter, zip me an email at mruggieri@ajc.com and tell me your favorite ABBA song. It will have no bearing on whether or not you're randomly selected as a winner – I'm just curious!

A few guidelines:

- Please submit by 6 p.m. Friday, Aug. 3; only one entry per email will be accepted.

- You must put “Mamma Mia” in the subject line, otherwise I will not see your email and you will have zero chance of winning.

- While this isn't a requirement, I would appreciate a follow on  Twitter  or Facebook .

Good luck!
