Always controversial threads... far more so than the reverse threads. Issa, Care of Night, Magic Dance have all been mentioned and I think all three and excellent albums.
Heartwind, Hardcore Superstar and Grand Design were all okay albums, imo... certainly not anywhere near the bottom of the year.
My list of prolific releases that were awful would look a bit like this;
Rox Diamond ; totally agree with above - shocking album
Rick Springfield - The Snake King ; what an absolute piece of shit. Massive fan of this dood, but this is dreadful.
Lee Aaron - Diamond Baby Blues ; I quite like some of her stuff, but this was a really bad album. Terrible to see someone trying to be someone they're not rather than just doing their thing.
Black Stone Cherry - Family Tree ; not too surprising as they only ever had one kind of okay album... but like Shinedown, they're back to their worst.
Ten - Illuminati ; this one's been mentioned, but a once-great band are now officially unlistenable, more or less. Horrid.
Panic! At the Disco - Pray For The Wicked ; not for most people here, but I don't mind these guys... kind of. This is just dreadful.
Salems Lott - Mask of Morality ; these guys are really quite bad. Ugly stuff.
Dare Force - Callin' Your Name ; no need for this to be released. Rubbish.
Rso - Radio Free America ; foolishly, I actually hoped for a bit from this one but it's very poor. I don't understand what makes two rock guitarists think it's a good idea to release drivel that doesn't showcase what they do at all.
Two Of A Kind - Rise ; after a ver nice debut, this was a massive step back - didn't like it at all.
Enuff Z'Nuff - Diamond Boy ; please just stop.
You Me At Six - VI ; very, very reliable modern roc band delivered their worst effort yet. Very sad, despite one excellent song.
Daughtry - Cage To Rattle ; another one who just needs to stop... or find his balls again. One of the two.
Roxanne - Radio Silence ; didn't expect the world from this, but it was an interesting concept to see them back. Thoroughly unenjoyable album for me, though, despite a few others getting joy from it.
TNT - XIII ; I did actually like that 'We're gonna make it' song - very catchy. But the rest - generally terrible.
Karo - Heavy Birthday III ; not really sure what this one was or when it was recorded... but it's awful.
Breaking Benjamin - Ember ; their sound has always been pretty tired, but this was their worst in a long time.
Bulletboys - From Out Of The Skies ; absolutely love the 'Best moment of my life' condescending rubbish song on this one... but the rest of the album is awful.
Tommy Paris Band - Tommy Paris Band ; really, really should not have released this one. Very bad.
5 Seconds of Summer - Youngblood ; one of my recent favourite bands join the bandwagon in completely abandoning any rock roots they had. Like a few others in this list, there's one absolutely killer song on this ('Talk fast') but the rest is garbage.
Smash Into Pieces - Evolver ; been a fan of this band in the past, but they've also strayed a bit and released a very poor collection of songs.
Shinedown - Attention Attention ; again... they only ever released one okay album so it shouldn't shock me... but this is just loud, annoying noise to me.
Airrace - Untold Stories ; disappointing collection from an otherwise decent band.
Reece - Resilient Heart ; it didn't surprise me that this wasn't good, but one album I genuinely couldn't figure out why certain people thought it wasn't bad. Just can't figure this one out because to me it's Reece at his weakest, by-numbers.
Fifth Angel - The Third Secret ; disappointing resurrection that shouldn't have happened. Not an awful album, but their discography didn't need it.
Terra Nova - Raise Your Voice ; how does an album get released with a production job like this?? Why? Sounds like a shredded ballsack. In typical Terra Nova form, some songs are quite good and others are awful. But it's all just nullified by the terrible, terrible "production" job.
Thirty Seconds to Mars - America ; sad to see what's happened to these guys. Another band that have more or less abandoned any rock sound. Again, like others, one killer song on this one very much in their older style... but the rest of the album is poor.
Kenny Leckremo - Spectra ; don't really understand this one. Really didn't work for me at all.
Reach - The Great Divine ; disappointing album after these guys offered some promise. This end of the list is getting better than the top half... but I was disappointed in these guys. Poor album.
Dynazty - Firesign ; they seem like a lost cause now. Any hope of them returning to a sound/style where they played interesting songs seems to have passed now. I feel like the last 3 albums have just been one long, average song divided over three discs.
Guild Of Ages - Rise ; great band with an exciting return... but my word is this a dud. Not a hook in sight on this one. So disappointing because of what they're capable of.
Slash - Living The Dream ; I've hated a lot of his solo stuff but still expect something these days. This was his worst album in a few years.
Fall Out Boy - Mania ; once-decent modern rock band getting worse and worse as time goes on.
The Red Jumpsuit Apparatus - The Awakening ; another once-good modern rock band as above... going downhill fast.
Tokyo Blade - Unbroken ; their last album was pretty cool but this was very disappointing.
Palace - Binary Music ; massive fall from grace here. After a very promising debut this was a huge letdown.
Jaded Heart - Devil's Gift ; these guys are gradually wandering well into Dynazty territory. Heavy is good. Shit songs, however, is not.
And I should leave it there. Plenty more disappointments like Vega and co, but nowhere near the worse albums of the year.
