Memories is a really nice song. It's catchy, it's reminiscent of Pinkerton (a bit...in the bridge), and it's amazing live (w/ Pat's little solo).
Clearly, though, it's not selling Hurley nor is it doing well at radio. It's had a high profile performance, tons of virial promo, and it's not doing much for the record. This has nothing to do with Weezer not having the same funding under Epitaph - it has to do with the fact that people aren't connecting with the song.
Weezer has never had a debut single not go Top 10 on Modern Rock radio. It's been sitting in the Top 20 bulletless or almost bulletless for weeks, despite all the promo.
Old fans deserted by the last few records need to hear this new stuff so they will buy it.
"Ruling Me" is easily the most radio-friendly Weezer single...maybe ever. Not only does it have that classic crunch, but the chorus is so damn catchy that even Pop radio would love it. It'll have no problem zooming up the Modern Rock charts all the way to number one, and other formats will follow after. I'm sure the video would be great, too - esp. if you guys are creative ("Buddy Holly," "Pork and Beans")...be nerdy factory workers or something, then go with the lunch room idea.
Regardless, Ruling Me needs to be released SOON - as in...NOW. That way you guys can bank on Holiday sales, old fans will now Weezer is BACK, and everyone can enjoy the glorious Ruling Me, which will pave the way for something like "Hang On."
Side note: Like "Keep Fishin'," and "Perfect Situation," and all the Pinkerton singles, you guys need to go in and make a new mix! The clipping must've been a mistake, but other than that, it sounds like a Blue song, so mix it like Blue (the same way Red was mixed)! There's way too much compression. Make the intro build up more (without making it longer), keep the crunch, make the drums cleaner, and maybe do a synth line in the chorus over the lead guitar.
