I tend to buy a lot of albums at the end of the year, or immediately after the end of the year, inspired by others' (including magazines') "Best of 2003" recommendations, so this will definitely change once I've heard some more stuff, but here's a preliminary list of my five favorites:

1. Radiohead -- Hail to the Thief
2. Outkast -- Speakerboxx/The Love Below
3. The Strokes -- Room on Fire
4. Yo La Tengo -- Summer Sun
5. Super Furry Animals -- Phantom Power

I wanted to only list 5 because if I listed 10 I wouldn't be discriminating enough, because I didn't buy that many new albums this year so far. But there are definitely a few more that I like, that may make it on a top 10 list when all is said and done.
