On top of the full album releases, everyone else released a single for their upcoming album release in May: Tori Amos, 311, Of Montreal, O.A.R, Paolo Nutini, New York Dolls.
I would also check out these acts, either they have already come out or about to: Bat for Lashes (every Indie magazine has done a profile on this songstress recently), Doves (highly anticipated), PJ Harvey and John Parish, Junior Boys, Royskopp, Camera Obscura, even Booker T. and the MGs are kicking out some new stuff!
My suggestion to you is don't get lazy with your music collection, I am talking a particular person I know that still has the Counting Crows on heavy rotation! There is SO MUCH great music being produced today and it is easier to get than ever. You can buy the web album for less than $1.00 on www.lala.com to play on any computer once you create a free account; you can also buy the MP3 and download the album for about .79 cents there too so eat it iTunes. Also try www.imeem.com, Hype Machine and MySpace to get a taste of the music for free.
My other suggestion would be to NOT read Rolling Stone, Spin, Billboard, or any other major music review until you have gotten a taste of the music and read a bio of the artist on your own. I don't think these guys review the album with an open mind; they use jargon that the average music listener does not want to follow, they are controlled by their word limit, editors, and they likely end up meeting the band they review at one point or another and most of these guys are punch takers not punch throwers, etc.
If you want to know what I will be listening to it will be in order: Silversun Pickups, Pomegranates, the first three tracks of the Eminem album, and Simon and Garfunkel right before I got to bed; then I will listen to everything else across the week because I don't know what I don't know. Enjoy your day!
