The landmark track was Kaiser Chiefs
"The Angry Mob".
Looking at my library as it currently stands, I have 103 artists although 'Various Artists' is counted as a 104th due to my taking songs from soundtracks by 'Various Artists'. I have 900 loved tracks although some of those are wrongly named/punctuated versions of tracks from when I started scrobbling from Media Player and it took a while to co-ordinate song titles with their playable versions here on the website. If I took those out, it would lose me a heck of a lot of scrobbles so, untidy as it may make things, I'm going to keep them.
I also have some tracks that are not playable on the website such as Cancion del Mariachi by Antonio Banderas
from the Desperado soundtrack, Rafael Nadal Dancefloor Superstar by Appart
and the Spanish Eyes/Lola, Lola medley from the Ricky Martin
live DVD "One Night Only". And of course there are tracks that were previously playable and have now gone missing like Torero by Chayanne
