So my iTunes library has increased to 10228 songs, 98% of which had been legally purchased . Ever since I crossed the 10000 mark my itunes has had some issues. it feels slower for some reason. for example, before when i used the search option beside the browse button, it showed songs as i typed letters. it now requires the entire phrase to be entered before something appears. not a big deal, but still... i enjoyed watching my library shrink down as i entered each letter...yes im weird like that. also ive been getting the revolving beah ball of doom more often now. actually it never appeared before in itunes. im running a 1ghz 17" PB with 1 ghz ram. is it normal to experience a little system lag when we have this many aac files?
