Way too many to list, but I'll mention that within the classical genre a couple of works that IMO are impossible to dislike are Prokofiev's Symphony No. 1 (the "Classical Symphony"), and Dvorak's Symphony No. 9 (the "New World Symphony"). Also, Chopin's Piano Sonata No. 3, Opus 58, which is incredibly beautiful IMO. Here is a nice video of a performance of the Prokofiev.
