Track number 40,000 was Sugar Man by Rodriguez. This was a latecomer to my library. Well, he was a latecomer to everyone in America. Despite being "more popular than Elvis" in South Africa, Rodriguez received no commercial success in the United States. Track number 40,001 was Inner City Blues, also from his first album Cold Fact.

I was on track to listen to the next 10,000 songs in under 365 days, which unfortunately didn't happen. It took me about 398 days. During this time I was still at my "temporary" job, although 15 months is a longer time…

Track number 30,000 was Slapp by Stalley, one of my favorite artists of 2011. Track number 30,001 was 330, both from the mixtape Lincoln Way Nights (Intelligent Trunk Music). I saw an interview where he explained that it took his sound engineers multiple tests on car systems to find the sound they wanted for the mixtape. I've used both songs extensively to test bass performance on my speakers and headphones. More on that later.

It took me 376 days to rack up my third set of 10,000 songs, the shortest period yet. This was helped along by…

Track number 20,000 was by Gorillaz, M1 A1 I believe. This time around I wasn't paying attention to make sure the milestone scrobble was a favorite song of mine.

It took me 425 days to get through my second set of 10,000 songs. In that time a load has changed in my life, but my musical tastes have more or less stayed consistent. One notable exception was my discovery of "Chiptune" music, 8-bit electronic stuff that was found in a lot of early video games. I added approximately 1500 chiptune songs to my library from the Keygen Jukebox. All…

I joined Last.FM 644 days ago and just played my 10,000th song. I've listened to a lot of great music over the years, and continue to find artists and genres that I haven't heard enough of. Nowadays I like listening to everything. For example, over the last two days I've been listening to Wu-Tang Clan, Art Tatum, Bob Marley & The Wailers and Apollo 440. Four vastly different styles of music!

To mark the occasion, I played three loved tracks for #9,999 - 10,001. All three are favorites of mine and happen to be featured in video…
