No, it doesn't.
The file compl.mp3 makes lame fail as well, in both cases (re-encode,
decode):

topolinik@cindy:/tmp/lametest.HDq5P/lame/frontend$ ./lame -q 0 -b 256
-m m compl.mp3 test_new.mp3
Error opening MPEG input file compl.mp3.
Can't init infile 'compl.mp3'
topolinik@cindy:/tmp/lametest.HDq5P/lame/frontend$ ./lame --verbose
--decode compl.mp3 test.wav
Error opening MPEG input file compl.mp3.
Can't init infile 'compl.mp3'


On the other side, the file is a regular mpeg stream:

$ mpg123 -v -t compl.mp3 
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3

Terminal control enabled, press 'h' for listing of keys and functions.

Playing MPEG stream 1 of 1: compl.mp3 ...
