18,125 songs 103.73GB. Mostly encoded as Mp3 (the ones I ripped from my cds's) and then the itunes store format for the rest. I didn't include my personal music that I work on because it's mostly chopped into samples and clips and would just pad the number.
I still have a fair bit of ripping to do, I find it a bit tedious so I just do a few albums here and there...and then I have the records to get through *shudder* now that is a pain to rip / separate...unless someone knows an easier way? I just play it through the line in and then manually stop after each track.
As far as listening to them all goes, I like(d) them all at one time or another for some odd reason...I like everything from classical, opera, new age, hip hop, r&b, rock, alternative, metal, then a mix of foreign stuff...
Oh and to whomever said that the prospective 120gb ipod is ridiculous...That would be the only way I could fit my current stuff on to an ipod

Right now I just use a shuffle for going to the gym. But if they came out with a 120GB ipod that would be terrific, then I would have an easier way to backup my collection !
