I believe storing an MP3 file in a database as a blob would be similar to storing an image file in a database. Neither would I recommend unless you are worried about someone finding the directory and downloading them. Usually it is best practice to store the path to the file in the database and then upload all the files to a directory.
If you have the means, most hosts offer a SQL Server database for 5 or 10 bucks a month. Much better than using Access.
