I think you definitely should buy POP. And here's why:
Dicotheque - One of Edge's best riffs in my opinion, the whole song is awesome, the melody and lyrics are pretty cool and the BOOM-CHAS at the end are awesome. Great opener and hilarious video.
Do You Feel Loved - We go from one of Edge's best riffs to one of Adam's best riffs. The man owns this song. Larry is playing some pretty cool stuff there too. Great song.
MOFO - Pretty much sums up the kind of sound they were after I think but this is really more intense in that way. Great and very revealing lyrics. It definitely doesn’t sounds like anything they had done before, it’s electronic rock and it works out great. Again Adam kicks ass in it. Would have been a great album opener too.
If God Will Send His Angels - One of Bono's catchiest melodies, I don't know how this song wasn’t a bigger hit single. Once again great lyrics. Some people say this song sounds undeveloped but I think it sounds perfect.
Starring At The Sun - And again great lyrics. I love this version but I actually prefer the acoustic version, believe it or not. Some very cool and interesting guitar stuff on this song.
Last Night On Earth - One of my favorite U2 rockers! This is definitely one of U2's best live songs, very intense and cool. Heavy guitar riff, great bass line, awesome lyrics and catchy chorus, perfect to blow your lungs out while singing it. "Who haven't been to bed in a week will be dead soon and still won't sleep..."
Gone – With an intro as good as Until The End Of the World this is another of U2's best rockers. Very revealing lyrics from Bono too here. The whole band sounds great in it; I love how the drum and bass work here. And Edge is the man on the live version with his guitar and backing vocals.
Miami - Very experimental song with very interesting lyrics. The riff is quite good too. Edge really came up with some great and very rock n' roll guitar riffs for this album as ironic as that sounds.
The Playboy Mansion - Some hate it, some love it. I love it. This is a very rich and colorful album. It's also filled with some of Bono's best and coolest melodies. And this is one of them in my opinion. I love the lyrics and the slide guitar. Amazing vocal harmonies from The Edge.
If You Wear That Velvet Dress - A 50's kind of song done with a 90's kind of production. It works even better live and the Jools Holland version is out of this world.
Please - Another great wok from everybody. And another of Bono's best lyrics and melodies. One of the most interesting songs U2 has ever done. Bono laying his hart out about his country, AMAZING bass and drum work (maybe the best on the album along with DYFL) and very interesting guitar sounds from The Edge. Worked great live too.
Wake Up Dead Man - A classic closer, doesn't sound much like anything else U2 has done before but doesn't really have anything new and original to it. It has some kind of melancholic feel to it but it’s very upbeat. Bono's lyrics and Larry's free-style drumming are the highlights.
