backup
You want to backup your data from last.fm? Then I'd recommend the script by libre.fm
lastexport.py by the libre.fm team

- the command to export is like this (adapt to your last.fm username):
python ./lastexport.py --user Erkan-Yilmaz
notes
- in case export stops in between:
- a. this command lets you restart the export at e.g. page 400 into file output2.txt (adapt to your username please):
- a. this command lets you restart the export at e.g. page 400 into file output2.txt (adapt to your username please):
python ./lastexport.py -u Erkan-Yilmaz --outfile output2.txt --page 400
- b. if you want to use import from below: you can concentate the output files with:
- copy (for Windows)
- cat (for Linux)
- b. if you want to use import from below: you can concentate the output files with:
- the exported file contains:
- date trackname artistname albumname trackmbid artistmbid albummbid
- time to export
- varies depending on your internet connection
- in the case with the 66 mins (for 2280 pages):
- after 34 mins: 1010 pages were processed
- last.fm library: refers to the python script's counting
- e.g. for the case with 2280 pages above:
- my last.fm account showed 729 library pages (each containing 18 artists)
- e.g. for the case with 2280 pages above:
last.fm Data Collector
for 139 library pages (ca. 2500 artists) I got a 5.3 MB xml file with:
perl lfmCOL.pl -xmlfile=Erkan.xml method=library.getTracks user=Erkan-Yilmaz
perceived problems:
a. missing packages at first start:
Can't locate XML/Simple.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at lfmCOL.pl line 52.
BEGIN failed--compilation aborted at lfmCOL.pl line 52.
solvable with: perl -MCPAN -e 'install XML::Simple'
b. not complete library exported (?)
atm I have 144 pages, but the tool just read 139
I guess this may be due to a database not being yet synced? must check
test system:
lfmCOL.pl - Generic last.fm Data Collector (last.fm -> xml), Rel. 0.4.0 - 2010-02-10
Debian 5.0.5 (lenny64)
perl 5.10.0

reimport your data to Last.fm
With this way:
- you have your data also backup'd on libre.fm
- (though personally I also run my own libre.fm server + backup there as well)
Howto
- a. make an account at libre.fm
- b. activate in options of the libre.fm website (menu Edit > "Connections to other services") your last.fm account
- c. say yes to "Forward Scrobbles?"
- d. now import the scrobbles to libre.fm which sends them to your last.fm account
- e.g. with this command for your username (more info here):
python ./libreimport.py Erkan_Yilmaz exported_tracks.txt
- e. though this bug was fixed, I've had similar bugs which increased the playcount different than originally :-(
Did this help you? Write a "thank you" here :-)
How long does this take?
import to libre.fm: in 1 min ca. 1320 tracks
This depends on:
- your internet connection
- if you have already imported to libre.fm (then it may be slower for tracks already there, since the operation needs to do more operations)
- it took 53 mins to import 70k tracks to libre.fm - which I had already imported there (tracks: #34748 - #104715)
- of course libre.fm has to forward to last.fm: time for that will come soon
